I’ve literally never actually seen an ancap successfully practice their ideas.
There is a community in Montenegro I know of trying to do that. It hasn’t yet desperately failed. It’s Russian, so may not fit you.
I also fuzzily remember a group of people planning of another such place like 10 years ago, but I stopped following them.
or loudly exclaiming that they’re the smartest and bestest and all their ideas are golden (ignore the fact they’ve never even tried to put them In place, just loudly yelled complaining about the world they exist in like cats).
How is this different from any kind of leftists except tankies?
