No word salad at all, its all Contract Law and Caveat Emptor. My definition of voluntary is not "theoretical" either, and you have no chance at demonstrating that people are forced or that it's involuntary, and you KNOWING otherwise won't change the facts that this is all based on contract law and you break a contract you pay, period, or contracts, promises and obligations won't mean anything. You are liable for paying taxes if you are working for the FED or are a dependent, if you are a citizen you MIGHT get away without paying taxes if you approach the situation by declaring that you're seeking information that will substantiate taxation as it applies to you, and you declare that to the people who are asking for taxes, so the tax assessor and you do it by correspondence and recording everything while using the Freedom of Information Act request to bind the servant's hands, but then again taxes probably apply to citizen depending on the State, so if you make "income" or use the Social Security Number, then you bet your ass they are entitled to their share and it's all LAWFUL, not only legal, as in maxims of law which hold REASON and LOGIC as the underlying principle.

No one is obliged to accept a benefit against his consent.
He who receives the benefit should also bear the disadvantage.
He who derives a benefit from a thing, ought to feel the disadvantages attending it.
He who enjoys the benefit, ought also to bear the burden.
He who enjoys the advantage of a right takes the accompanying disadvantage.
A privilege is, as it were, a private law.
A privilege is a personal benefit and dies with the person.
One who avails himself of the benefits conferred by statute cannot deny its validity.
What I approve I do not reject. I cannot approve and reject at the same time. I cannot take the benefit of an instrument, and at the same time repudiate it.
He who does any benefit to another for me is considered as doing it to me.

If you are earnest at discussing these issues you'd be asking questions, and not slinging around accusations of NONSENSE, what word salad?

Do I have to break down the idiotic reasoning of "Declare you don't have to pay taxes in the IRS offices" after I have said that you better not enter into controversy and that even if I were to do that it certainly WON'T demonstrate anything about the issue of taxes being voluntary. You seem to keep up the pretense that all those people were forced to pay taxes, they refused and were murdered or kidnapped. I say that that's ONLY an interpretation and not actually what happened, I see the flaw of the first couple you gave me, by their performative surrender of their Sovereignty and Peace by walking into their court and saying Yes to their nom de guerre, yes to their name of war.

This is very deep and it would flourish into an intersting discussion but then you'd have to approach this SENSIBLY (instead of persisting to repeat the same assertions that cannot be backed up or demonstrated concretely at all) and give me some serious consideration and posit whatever question you have for what doesn't make sense or what you don't understand or know about.
