Not quite. The common law applies to all people, anywhere, everywhere. It's the natural, universally accepted law. You cannot cause harm or loss or breach the peace or commit fraud in your contracts. It covers everything. Theft, murder, perjury, public nuisance, etc. Admiralty law (statutes, codes, regulations) are specifically restricted in their scope and applicability to the members of that society. A statute is defined as a legislated rule of society, given the force of law. A society is defined as a number of people joined by mutual consent to deliberate, determine, and act for a common purpose. So, statutes are laws to people who have given their consent to be a part of the society. It's like if you have lived on a piece of land your entire life, and some organization came in, claiming to be the government of the land, and tried to get you to pay taxes and follow their policies. You'd tell them they had no jurisdiction, no authority. Because they don't. It's like saying marijuana is illegal in the United States and trying to enforce that in Amsterdam. Doesn't work. No jurisdiction. And it's not because it's a separate piece of land. The fundamental laws of the land provide that all men are created equal and that governments are instilled among men to protect inalienable rights, and that when government becomes destructive of these rights, it is the right of the people to alter/abolish it. You can declare sovereignty and there is nothing anyone can do about it without a gun to your head.
Actually, yes, I do. The number is generally on the back of the birth certificate and it is evidence of a bond created in your name. In America, for example... FDR created a trust in 1933 (and there is also a trust created by the Constitution) of which the people are the beneficiaries. The Secretary of Treasury is the fiduciary of this bond and it directs the funds in it to your local representative. I think it would be your state's Congress member, not entirely sure. In Canada it's your provincial representative in Parliament. You can send notice directing these funds for debt set-off. Several people have done this with their student loans, credit card debts, etc, and it has worked. The debt simply moves to zero.
