For US citizens it is really hard to get rid of their citizenship. And you pretty much have to pay US taxes as long as you are a citizen no matter where you live (and thus implicitly support the government).

Not sure about that. I've heard that you just need to go the embassy and you can get rid of it quite easily. However getting citizenship of another country may be a bit difficult for anyone in these times. You don't really want to remain stateless right?
