I'm eternally disappointed that none of these libertarian projects even manage to survive long enough to hit the "oops we just reinvented government and taxes" stage.
Libertarianism is a spectrum. The majority believe in some form of government, just limited in what it can do to varying degrees. The are also anarchists, yes, but that's not all libertarians.

They don't want to actually create anything for anyone else or the messaging would be different.
It's the same energy of a kid running away from home to the tree house in the yard. All they want is to have all the benefits of society (imagine if they were barred from reentering their home country or traveling anywhere else because Pirate-Monaco-Dubai-island(tm) doesn't have real passports) and not be held responsible for their destructive behavior and impulses.
