I wanted to delve a little deeper into the concept of rights....I apologize for skipping some stuff, but I think that area deserves a better explanation than I gave it.
The first question we should ask is "Who needs it?" In other words, why do we need rights in the first place? As I pointed out, a person can live just fine on a deserted island without ever dealing with rights--thus, they are not inherent in the human condition. Why should we bother with them?
The answer is: IF we wish to interact with others, THEN there needs to be some set of guidelines, some rules. Otherwise there's simply no posibility of interaction; it'd be a complete toss-up as to what would happen in any interaction. There'd be no possibility for trade, which means no posibility for specialization, which means we'd each have to survive only on what we could gather from the environment ourselves, etc. The most fundamental of these--those rules which are absolutely necessary for maintaning a society--we call rights. Those rules which can vary from society to society are called manners, customs, etc. (For example, we all have to write things down, but exactly how we do it--what instruments we use, the characters we use, the order we do it in, all that--is highly variable.)
It's like bsaeball. You can go your whole life without ever learning the rules of baseball--but if you wish to play baseball, you must follow those rules. Similarly, you can live your whole life without being part of a society (though the lives of those unfortunate few who have are both horrifying and brutally short)--but if you wish to interact with people, you've got to accept the concept of rights.
Unlike Libertarians (at least the ones I know), Objectivists do not consider rights a primary; rather, they are derived from more basic premises: Each person is an end in themselves, for example. (In fact, they can all be tied back to that premise--rights basically boil down to "Don't treat others like you own them".) Rights CANNOT BE primary; as was demonstrated in this thread, rights are derived from specific ethical concepts. A socialist will have a very different set of rights from an Objectivist. Their rights will still boil down to fundamental rules for social interactions, though. It's impossible to imagine a coherent and rational set of rights applicable to a person all by themselves, with no potential for interacting with other people.
The primary rule for interacting with others in Objectivism, as stated above, is that other people don't belong to you. The rights Objectivists believe exist reflect this. You can't kill others, because they aren't your property. You can't take their property, because it's THEIR property, and doing so assumes that you own them. You can't censore them (in Objectivism, this refers only to government action; the right to free speach does not mean anyone owes you the means to speak), because you don't own the property they use to spread their message and you don't own them. In contrast, you CAN kill a pet, or take things away from a pet, or stop a pet from growling/barking/hissing/what have you.
As was pointed out, this can get complicated in cases where the property in question is a complex entity. Who owns a river? Tough question to answer. However, more derived concepts--the customs of the land in question--can be used to determine this. Think of them as house rules. The actual application of these concepts is the realm of (proper, under Objectivist philosophy) political philosophy, an area I haven't researched that much. But the fact that practical application under complex conditions becomes complicated is not disproof of the concept; f=ma can become difficult to solve under complex physics problems, but the foundational concept--that force, mass, and acceleration are related in specific ways--remains constant.

So. Your description mentions two things: property and contracts, which sound interesting. How should property be determined, in the context of a Minecraft-like game? What could be some in-game mechanics for implementing useful contracts between players?
This is something I've given some thought to--I wanted to start a Gult's Gulch server at one point. Unfortunately, it's not possible; there is not sufficient capacity for innovation in Minecraft to reflect the real world.
That said, a very good way to do it is the following: Anything not claimed is considered wilderness (as in the real world). Attacking villages is immoral; villages should be considered claimed by the villagers (or, ideally, removed entirely). Property, at least initially, consists of the area you develop. As a custom (NOT a right, but an enforceable rule of behavior none the less), property above ground will be delineated by a fence or wall. Property below ground is trickier; I'd say that you own anything below your claim, to be sure. If you fence off an underground area, it's yours (you cannot remove other claims, and this cannot violate claims above ground!). Players who break into unfenced mines in the wilderness will not be held criminally liable, though basic courtesy demands they fix the damages. And, due to the nature of the game, you can only build structures above either wilderness areas or your own claim--building things that cause monsters to spawn in other people's property is a violation of their rights, and would be treated as such.
Alternatively, each claim can include an area 10 blocks above the highest point, and 10 below the lowest point, at the ground surface. Claims underground would be 20 blocks above and below the claim, or until they run into the edge of another claim, whichever is less. I've seen the equivalent of both in the real world.
A claim is necessary because in order for something to be your property other people must be able, in some way, to recognize it AS your property. I don't mean you ahve to have your name on everything you own, ro that people can take things they can't immediately identify owners to; rather, if a person acting in good faith cannot determine if something is property or not, they have commited no transgression; errors of ignorance are not moral failures, nor can they justifiably (or in justice) be considered criminal offenses. Civil, maybe, but not criminal.
Contracts can be written on books, and it would be extremely useful for someone to keep track of said books. In fact, I'd say this is one legitimate activity of any governing body: ensuring a record of all contracts. There would also have to be a police force to ensure compliance with the laws and to enforce contractual obligations. Personally, I think a tax on all contracts is justifiable; it's payment for services rendered, after all (a rather controversial stance in Objectivism). Police aren't free, nor should we expect them to volunteer thier services. There'd also have to be a judge/arbitor for settling disputes and determining when (if) violations of rights ro contractual obligations occur (multiple if the numbers got high enough). This judge wold have the power to confine the player's avatar, or remove the claim, or transfer the claim (as damages), or in extreme cases remove the player from the server (the equivalent of exicution). If there is no next of kin, the claim would revert back to wilderness.
After that, players would be on their own. They could work together if they wished, or separate and live as hermits if they wished. They could create a contract that allowed them each partial ownership of a large claim, or they could rent claims from each other, or whatever they wished.
