Amazingly, I actually have knowledge, both real-life and case related, to help you along in this journey.
The movement is called the "sovereign citizens" movement. Feel free to look up information online but take everything with a grain of salt; the original movement started from white supremacists, and making their claims will have you come off a bit like a backwoods redneck.
Some basic sovereign tenants are that the US never obtained proper ownership of the colonies and therefore they are not beholden to US laws, including taxes, property rights, or the ability of law enforcement to arrest or detain them. I have seen many, many, many poor people buy into self-help law-form schemes to get out of foreclosure, taxes, jail time, and many more. I have never, ever seen it work, and I've been working in law for nearly 15 years.
It all looks very good on paper, especially to lay people not familiar with so very many case laws and codified laws to the contrary. I assure you it doesn't work. Our government may be a sham and a lie, but that lie has been perpetuated for over 200 years, your sudden documentation of your body as a country unto itself and beholden only to heaven will not get you anything but some heavy court fees for obstruction and late fees on your taxes.
Look instead into how to create "legal" tax havens like non-profits and education centers, how to co-op land and buildings, and how to skirt building codes that require certain building shapes and features. Knowing the law, and working within it's short comings, will be the best way for you to live the free life you want.
