Getting out of it is simple, however, IT IS ANYTHING BUT EASY. In a nutshell, you secede, i.e. formally withdraw FROM MEMBERSHIP in the governments, quit using a taxpayer identification number, and waive ALL member-only benefits and privileges.
But before you make the leap, be sure that you understand what you will be giving up, becoming independent is NOT painless, we've strayed way to far from that path for it to be so. You may lose job, family, friends, and more.
Also, you need to know that although being sui juris, i.e. being self-governing, has its benefits, it is NOT a suit of armor, it will not make you bulletproof.
"The Matrix is a system, [Noel]. That system is our enemy. But when you're inside, you look around. What do you see? Business men, teachers, lawyers, carpenters. The very minds of the people we are trying to save. But until we do, these people are still a part of that system, and that makes them our enemy. You have to understand, most of these people are not ready to be unplugged. And many of them are so inured, so hopelessly dependent on the system that they will fight to protect it." ("The Matrix")
 You are NOT asking permission, you are making a Declaration of Independence because, "Dependence leads to subservience."(Thomas Jefferson) Remember, the STATES have submitted themselves, and thus their "citizens", to the dominion of the Federal Government, so you must withdraw from membership in these subsidiaries as well.
"It is an inarguable historic fact that the Declaration of Independence was a declaration of secession from the British Empire." ~ Joe Wolverton, II, J.D. [Jurist Doctor or Doctor of Jurisprudence]
"The Declaration of Independence was and is, no more and no less, than a document justifying secession." ~ Donald Livingston, PhD--Emory University
 • Invito beneficium non datur. No one is obliged to
accept a benefit against his consent. But if he does not dissent, he will be considered as assenting.
• Cujus est commodum ejus debet esse incommodum. He who receives the benefit should also bear the disadvantage.
