I've long considered myself more of a libertarian or perhaps classical liberal. It's not so much that I don't agree with voluntaryism, it's just that it seems to be more of a utopian ideal that wouldn't work out well in the end. Not because of the ideas themselves but because there will always be a large enough or powerful enough segment of the population not wiling to abide by those ideals to make it unworkable in the long run.

Having said that, we are so far from that type of society that the goals of all such groups are practically the same for now (or should be). Limit government as much as possible.
