In theory I support the elimination of taxation and a purely volitional society, but I recognize that such a thing is likely a very long way away. What we have now is not even close, and trying to shoehorn it into that vision prematurely will not work. That kind of moral futurism should not blind us to chances to radically improve human life here and now while working pragmatically within the bounds of the political realities we have.
One also must ask the question: given that the abolition of force and fraud is a moral long term goal, what sort of society would we want to build that would be likely to evolve in that direction? I don't think crony capitalism with fascist tendencies and no social safety net seems like what you'd want. Seems like that would be more likely to regress back to feudalism... which is exactly the historical path that we seem to be on. Regression to feudalism takes us further -- much further -- from that goal.
Seems to me that the precursors to a volitional libertarian state are radical reductions in violence both within and between nations, a highly educated and healthy populace that is capable of taking care of itself, and the abolition of caste systems (e.g. sexism, racism, classism, guild systems, etc.). A basic income is a step in that direction.
