> but what is a "legitimate tax"?

One that goes through all three branches of government, the way it's been since we decided "no taxation without representation" is how such things should be collectively implemented.

If a citizen's stance is there is no such thing as a legitimate tax, perhaps there should be a legal process for banishing them from all public services, including roads, electricity, telephone, fire and rescue services, etc. and make consuming them a crime. But I guess even that would be a problem because we need to pay for the justice system that would prosecute such a sovereign citizen that breaks the rules...

Basically an "opt-out" of modern life almost in its entirety. I think most people that subscribe to "no legitimate taxes" might be surprised how isolating that would be if they actually think it through.

To be clear, I don't think this is a good idea, it's simply a thought exercise.
