This nonsense about libertarianism being "refuted" or "attacked" by skepticism is silly, unless one is referring to certain claims of the "If X, then Y" nature, but then again that's true of any idea or political ideology. So whenever one of you says that, it's merely a repetition of your disagreement with the philosophy tailored to the audience of this board. Not impressed.
Right and wrong are not <I>real</I> things. Creations, spooks, figments of the imagination, sociocultural or individual creations. Behaviors. Preferences of behaviors. A preference for a certain type of behavior cannot be right or wrong.
Talk of rights being "created" by society is also nonsense. If a right is something that society lets you do, then one cannot claim that society has ever violated a person's "rights," and slaves during a time when slavery is legal are not having their rights violated because at the time they did not have rights. The moral intuition most people seem to have is that rights, or at least "how individuals should be treated." When Darat and others claim that rights are "created" by society, he is merely saying that society ("most people") either do or do not allow certain conduct, and also demand certain conduct in certain contexts. Saying anything else is just introducing metaphysical baggage in an area already implicitly full of it (ethics/metaethics).
Since all morality ultimately comes to arguments over ice cream flavors, discussion on these topics is impossible. Moral statements are statements of values, preferences. Yes, I am an emotivist.
In this way a libertarian (such as myself) does not really need to care about the empirical claims many libertarians make, most annoyingly ones from some philosophically nonsensical "Austrian school" which fancy economics a supposed "a priori" science.
One can ask, what authority does "society" (most people) have over the individual human being, myself or others? One may say "might makes right," and I'm inclined to agree with the sentiment behind it, except I would merely state, "might makes." And my morality, my feelings, are not particularly tickled when talking about the wants of the many crushing the needs of the few, or what have you. Libertarianism ultimately may begin at the realization that there is no great duty one has in carrying out his or her life; the government agent and the mafia goon are both equal as neither has any validity with their demands when you don't recognize them as being proper authorities. Why cater to the hungry demands of "most people" anymore than "a certain few?" Why care what the majority personally wants from you? One is not born into the world with inherent obligations towards others anymore than one is born into the world with such things as "original sin." All politics ever really is, is, some group, be it a majority or minority group, stating, "we want this, we demand this, this would be good for us, you don't need this, we'll take this," or, "we dislike your conduct, it is displeasing to us, we will force you not to do it or hurt you if you do." That is why walking outside naked is illegal even in most of the most "democratic" countries, despite the utter lack of damage it does to other beings--societies have become horrified at the sight of themselves and democratically decide to harm those that walk around through nature with their outer form unshielded in certain areas. It is a disagreement of taste that produces strong emotions, and strong emotions get people to act.
The notion that anyone has any inherent "authority" over another or one has an inherent notion to obey another individual, or produce certain conduct for another's benefit... I just find it laughable, really. It really is petty.
Skeptics like to appeal to authority, to society, to majority opinion in general, in moral matters. Those higher in intelligence and education tend to be left-leaning; I suppose it is some sort of cultural dynamic that shapes this. My experience with the left is is that many left-leaning individuals have a certain respect for authority and obedience that is also seen in the right but takes on a far more utilitarian flavor.
A good portion of the criticisms against libertarianism seem hold the world constant and think the world would not/could not adjust when that is not a settled fact (e.g., no FDA means no safety testing). Libertarians go to far in claiming that safety testing would be better due to competition or whatnot, but everyone else, too, goes too far in saying that the current paradigm is the best way. Or say, in regarding roads, that the system would be convoluted and too messy to bother with. (I wonder, in a magical hypothetical libertarian la-la-land, would people there, used to and thus content with their paradigm, would they make the same complaint about the bureaucracy of government?) when in reality a libertarian system, grown organically, may very well adopt cultural conventions on its own. Nobody has to tip in the United States; people do it anyways. Of course speculating on the nature of such a system is also a waste of time.
One thing that gets me is the skeptics, so concerned about protocol, and following the rules to a T, makes me wonder if they're not, as a group, all robots that has never been out in the real world. In the real world, the law is poked, prodded, misused, interpreted and re-interpreted; one cannot expect to stay safe from it if only they "play by the rules," because the rules, being merely words on paper that require interpretation, are dynamic and ever-changing even without new laws being passed. Sometimes the law is even ignored out of necessity, and how can one know which laws are and are not enforced? Some (many) certainly shouldn't be. And then, in the real world, protocol is never strictly adhered to because bored and tired humans are tasked with carrying them out. Safety regulations are skipped in restaurants, regulators skip over breaches in regulations because they don't want to file additional paperwork, grad students fudge a number or two in the data because they can't read the messy handwriting recorded on the sheet or don't want to restart the entire experiment, or start skimming over essays they need to grade due to strain, stress, and time constraints; the entire world works this way and it makes me wonder if skeptics have ever seen the dirtier, grittier, "real" parts of life. All the rules and regulations in the world, all the system-building, won't save you either, especially when it's almost never preventative and mostly just acts to punish those that disobey the will of the dominant group.
