There's an easy solution to that - renounce your citizenship. What's that? You want to keep your American citizenship? Then you must abide by the social contract underlying that grant of citizenship, which comes with certain benefits/obligations no matter where you are in the world.
Nonsense. First of all, I am giving up my citizenship. But the US and North Korea are the only countries on this planet stupid enough to think people who don't live there anymore owe them money.
