If you only read Rothbard and his ilk, it did. But just like Marxism had thousands of years of proto-projects and inspiration, the thought behind Ancap has been around in practice for centuries.
So non-ancap nations influenced by ancap count?
The only countries to be ideologically pure in anything have been hellscapes, so I’d say being inspired is probably the best example you can get.
I guess you won’t call cryptocurrencies a success of ancap ideology.
You literally had to recreate centralized exchanges for crypto to succeed, and through that, you rebuilt everything that’s wrong with traditional currency but transferred the control from democracies to private citizens.
