Taxation is not voluntary. If you don't pay, there will be penalties. This is coercion. "Nice house you have there - too bad you didn't pay your taxes..."

If the collected money is then put to a purpose you don't like, or is incompetently managed, what can you do? Nothing in any realistic sense.

If you would have liked to have been generous with the money instead, too bad.

As an aside, tax rates are pretty meaningless. Revenues are at record levels.
