False dichotomy, there are other options that both don't lend any legitimacy to the state and allow you to live a pretty good life these days. Especially for people with technically advanced skillets. The world is much bigger than the tax farm you were born in which claims dominion over you, and outside the borders of that farm, its powers are greatly diminished.
 Obviously there are exemptions for foreign earned income, but if you're in country with lower tax than the US (of which there are a fair amount) you could end up paying the US taxes on money that has literally nothing to do with them. Worse, if you're married to a native of that country and must file jointly in the new country then the US expects you to file jointly with them too and pay taxes on your spouses earning.
