I agree with this, Ziggers.
In addition, I would say that, like freedom, libertarianism is not something that can be imposed from above.
It's a movement that demands absolute responsibility from all (adult) members of society.
It's a paradigm shift in consciousness; not a political movement.
(Or something along those lines, anyway.)
That's really the issue. As long as not all people are perfect socialists, libertarian society cannot succeed. If even 1% of people put their own immediate interest above the community interest, the situation will come apart at the seems. You need the Amish. You need a community with very little in the way of individualism and very tight community conformity. And even then you need to be able to exile those that do not do exactly what is expected of them at all times.
And for the population at large, you're just never going to get that.
