I seriously doubt whether half of the anarcho-capitalists I know have ever read Rothbard or Mises.
Because… they generally are just repeating “conversation” libertarianism. Like stuff that libertarians say on Facebook and Tumblr.
…and usually don’t understand the actual theory when we start talking.
What you are essentially saying is that people who aren’t Rothbard or Mises (who wasn’t an AnCap) can’t independently conceive the idea of anarchy or Anarcho-capitalism?
The beauty of anarchism or Anarcho-Capitalism is that it is very logical. One can easily deduce the theories and ideas of anarchism single handedly, without ever having to be introduced to the great thinkers of libertarianism.
Anarchy is logic.
