Alright, let's take this further: the argument is that we would support the poor through voluntary charity, yes? Now let's say after 10 years, charity turns out to be woefully inadequate. Let's assume that -- while the world has not devolved into chaos and anarchy as a result of a lack of government -- that some are suffering because not everything went as planned. There's slums with no police protection because everyone that lives in the neighborhood can't afford it. How do we approach that? Are some things up for socialization, or is it all strictly no go, no budge?
Sure, the poor ain't doing so hot right now, but in order for the change to be worth it, it's not enough to be different. It's got to be better, and noticeably so. The problem is better is subjective, and not everyone will agree on, let alone know, what better really is.
Oh, I'm fairly happy to take things piecemeal. If things don't appear to be working, back off and adjust approach. Obviously, I believe things would not tend to end up that way (though government action has created a huge underclass that would have to be accounted for) but I'm not one for big schemes that have to be implemented in one fell swoop (just look at Obamacare for how that kind of thing goes).
Basically I see it like a big game of Jenga. There are some pieces which can be taken easily and others which require the removal of other pieces before they can be taken without collapsing the whole tower. Fortunately, almost every step that is taken to improve freedom should make the next one easier.
