To the Kyle Wagners of this world, taxation is necessary. Hell, just today I had him telling me that a real libertarian must be prepared to defend taxation. Their view is that a) some goods can only be provided by a "state" and/or b) if everyone benefits from something, they should all pay.
Which are both utterly absurd points. Coincidentally, none of these people have been able to provide evidence for either claim. They also can't seem to prove that a "state" is morally superior to anarchy, without contradicting themselves.
Sociopaths, man. Sociopaths.
