In extreme cases, sure. Or you can elect officials who shape the government in a way you feel is more to your tastes.
Sorry, but that is just plain 100% wrong.
Go ahead, try to leave the USA and its control over you.
Did you know it takes on average 4 years and $50,000 just to denounce your citizenship? Does that sound like something that everyman can just do at a whim?
If you move to Spain today and make $100,000. you have to pay Spain the tax you owe them, PLUS you have to pay income tax to the US government.
No matter where you work in the world, as long as you are a US citizen you MUST pay income taxes.
That doesn't sound like you can remove yourself from US government control by simply moving away from the US like you claimed.
