US government, yes. But that's because of the death penalty, isn't it. Something the US has in common with countries like Saudi Arabia.
You seem to confuse private and public property. It the government is the owner, you pay the government. There seems to be a quirky idea that if an individual tax payer does not agree with a particular government expense, one can object to that expense. You can, using your democratic rights. (Try that in Saudi Arabia. You are free to move there - and to be taxed there.) If you disagree with taxes sic, create an anarchic country. But don't complain about individual taxes or taxes in general. That's simply extremely short-sighted. Otherwise, exercise your democratic right to complain; it's paid for by tax. You may even found a party to abolish (particular) taxes. Or start a movement within a party to do so. It has been known to happen.
However, none of the above has anything to do with morality. Governments have expenses, so they have taxes. That's all there is to it.
