You consume the services of a country regardless of where you reside when you are a citizen, even if you don't consume much. But, yeah, Trump really fucked dual US citizens on that one (before 2017 you "had to pay US taxes" but you deducted the taxes of whatever country you were living in, which given the US's lower tax rate meant it was meaningless.)

I'm fine with you having to renounce your citizenship if your point is "taxes are theft" and you want to avoid them. If you wanna go your own way, fine. But then go your own way.

All wrong. 1) I don't consume any "services". 2) Sure you can deduct your home country taxes, what are you talking about.
