It seems to me that it is almost asserted taxes are voluntary because we “collectively” decide to impose them, for purposes we support.
But obviously “we” is a majority (perhaps a small on), not a unanimous consensus. The benefits don’t accrue to those who pay either, and you may oppose what your money being used for, such as a war in Iraq, or abortion to recognize a spectrum of issues.
Taxes are a necessity, and I think using them through democratic processes for public purposes even redistribution of wealth within reason is legitimate. They are however also coercive, and it isn’t stupid or nonsensical to believe so.
