I stopped being a Libertarian around 10 years ago. I could write whole essays about, but it started when I realised that the world was already anarchist and if Libertarian societies were superior then they would naturally outcompete other societies and we would all live in an Libertarian utopia right now.

Not for the lack of trying. There have been more than a handful of Libertarian city takeovers and sea-steading projects, and they all end in similar, predictable ways. The sea-steader/new country declarations fail to defend "their" territory against an actual military, and the libertarian towns run out of money and/or people willing to live in a free-for-all society without common services.
