Here’s a funny recent one:

https://newrepublic.com/article/159662/libertarian-walks-int...

“When a group of libertarians set about scrapping their local government, chaos descended. And then the bears moved in”

But surely there’s a million reasons why these were not True Libertarians, they were just doing it wrong, and the ideology is actually sound. Just like with communism.

IMHO, Libertarianism fails not by collapse but by success. Any movement in the direction brings economic and social freedom, but in turn creates soft times in which a society's pendulum shift back to larger government is inevitable.
