Your gun won't protect you when Big Brother comes knocking at your door. Even if you can make it too difficult to actually take you by force, which I doubt you realistically can, the state can simply make your life sufficiently difficult (e.g. no way to get employment, no credit lines, no education for your children, no electricity) that the act of actually imprisoning you doesn't matter anymore.
