Seriously? First, read what he was in response to. Some fairly minor critique about libertarianism. He starts his post with:
Some key illuminating points to look into:
He is not being sarcastic, ironic or presenting the end result of a slippery slope. He is actively defending all those things. The reason his entire second point is about the gold standard is the parent said how libertarians stupidly support the gold standard, and he was acting like that was an idea worth defending.
You:
This is why I think you didn't comprehend him. He is clearly not advocating that a line-item veto on tax forms should exist, so showing that that would be a stupid idea does not refute him at all. If he is really an anarchist as you suspect, he wouldn't be advocating that tax forms exist at all. But he's not directly advocating for anarchism or the abolition of all taxes there,
Him
The reason I pay taxes is I don't want to have someone steal my shit, throw me in jail, and/or shoot me. Not because I think it's right or I support what's being done with my money. I think most people, if they had a real view of most of what's being done with their tax dollars, wouldn't support it either.
The guy is a libertarian. His ideas are stupid. A line-item taxpayer veto, which he advocates while recognizing that it will end government, is stupid.
And at this point you're either willfully ignorant of what he said, or are trolling. Or, I'll made this allowance, I'm willing to believe I misread him. But you're going to have to do something besides mere assertion.
Now, you seem to be at least sympathetic to the libertarian side yourself (drawn from the connotation of your "predictable responses" to "what if I don't want to pay taxes", as well as the fact that you take the non-aggression principle seriously). If you want to discuss that on it's merits, I'm more than happy to. But let's not pretend that there is some deeper issue.
