Yeah, what would you expect? If you leave the social contract, you have all your rights back. Then again, you are no longer entitled to the protections society affords you. In an abstract version of this, upon completely leaving the system you were born into, you are subject to the state of nature and so the state can kill you if it feels like it. Or it can enslave you, or take all your property; what are you going to do about it?

You don't have to pay taxes, though.
