A tax is a subscription fee for the privileges of citizenship. There are many millions of people who would happily become "subscribers" in return for becoming US citizens.
Salary taxation usually means you are earning your dollars by being part of a functioning society.
There are billions of people who would happily become "subscribers" to a US job market, even if the offer required that 50% of their income was ritually burned for no benefit to the “subscriber”.
Now capital gains are perhaps a different argument…
If you fail to pay the subscription fee for your gym, but break in to use the equipment anyway, it might.
You're pushing the analogy too far. You're not an autarky, there's plenty of stuff you have to pay for that isn't optional (e.g. food, shelter, etc.).
