Maybe because in real world the choice is between fixed alternatives and not imaginary scenarios? Even if you think US taxes are way too high and immoral, it's not like you can live in a country like US but without taxes. You can live in a country much worse than the US with taxes, or in US with taxes, or in a country with failed government where there are not taxes but instead people might just kill you on the street. So you might make non-ideal choice, knowing it's not ideal, but it's best of what you have. Every country has its benefits and its flaws, and accepting it as it is doesn't mean one has to be blind to the flaws.
Maybe there's a correlation for a reason? Namely that functional governments which keep the peace and provide services to their citizens need income in order to operate.
What US government is doing goes very far beyond "keeping the peace". Only the discretionary budget is 1.5 trillion dollars. Americans would be a really wild bunch if it required $1.5 trillion to "keep the peace".
