>>Protect by a world superpower military and diplomacy,
That's the argument the British crown once made for taxation without representation. It wasn't very well-received.
A country is obligated to protect its own borders and demand commensurate payment. I don't see a reason to pay for American military expansionism if I'm kept safe enough by my country of residence. Anything beyond that is wasted tax dollars or adventurism with the US government's own motives in mind. I shouldn't have to subsidize either one.
>>welfare and social security,
EBT, food stamps, COBRA, etc. aren't recognized outside of the United States. Social security is not a benefit. It's a Ponzi-scheme with a gun to your head taking money that was already earned and delaying it until you have strong chance of dying from a heart attack.
>>a stable place to return to in the case of trouble,
That's an argument that can be made for most overseas citizen of many countries. Yet these other countries have not fallen to shambles on the basis of lacking global taxation. There's no reason for me to pay for a "stability" I'm not in a longitude and latitude to benefit from.
On the contrary, there is a case to be made that United States is quite unstable itself as it has failed to contain a disease within its own borders and has also chosen to violate property rights under its unconstitutional eviction moratorium without providing just compensation. Even pre-COVID, some areas like Chicago and Los Angeles have had crime ratings high enough to compete with entire countries.
>>a country that ensures development of vaccines and provides them for it's population in the case of pandemics.
So can India, China, Britain, France, Italy, Germany, Australia, etc. Why should I pay the United States if I received my vaccine from these countries' labs and and medical resources instead?
>>medicare (or similar) for all as well as some other social benefits that make sense to enable more risk free pursuit of happiness and simplify employment.
An American citizen can't use medicare in a foreign country. Just like how a British citizen can't use NHS services in the United States.
The pursuit of happiness is a negative right, not a subsidized one.
