That kind of concept would work with enough mobility to just leave states you disapprove of. I like to think a huge amount of political inertia in the last 30 years has been due to the lack of any new frontiers to settle. And it is hard to voluntarily withdraw from a state if that also means you have to somehow get accepted into another one, since almost every square inch of habitable land on Earth is state controlled, even Antarctica.
