U.S. citizenship comes with benefits (voting, etc) as well as drawbacks (taxation). If you don't need those benefits and you don't want the drawbacks, renounce citizenship.

That said, I was being a little loose when saying citizenship. The U.S. has various laws many of which are regarding taxation of business within its borders, with entities housed in its borders, or citizens abroad. They will seek to enforce those laws. I think that's for the most part that's fairly standard.

There are of course a myriad of ways in which the issue becomes more complicated, and I'm not trying to claim the government can do no wrong and all their actions are justified, I just think it's important to look at the issue holistically. The government should be capable, which appropriate checks and balances, to enforce the laws. People should have the ability to have some expectation of privacy from the government unless there's a specific reason the government seeking otherwise that's valid.
