What do you make of the lack of [significant experiments in the real world](https://en.wikipedia.org/wiki/List_of_anarchist_communities) (note that most examples on that page are collectivist societies, communist #libertarians, etc — not experiments where all property is private)?

I get that a modern nation doesn't sell a region or a province to a group of like-minded individuals to let them live and interact as they please, and that even if that were possible, such community would still depend on the “outer world” for lots of important things.

Still, isn't is suspicious that there aren't at least a bunch of long-lasting, functioning libertarian experiments where members voluntarily ditch outer courts and laws, shun subsidies and quotas of any kind, rely on an inner grey market to conceal income and wealth as much as possible, rely solely on voluntary agreements among them, etc?

With so many passionate supporters worldwide, why isn't that happening, at least to the extent it's feasible within the framework of existing jurisdictions?
