When I was 7, my family took a trip to Italy. We went to the Vatican. While we were there, we discovered a little side door that was open and went inside. Inside were a dozen gold carriages used to carry Popes before they got cars. At 7 years old, I asked my parents why they didn’t sell these and feed starving kids in Africa. Even a little kid can see the injustice.
Maybe so. I don’t think it’s evidence that anarchy is the best solution, just that neolithic societies without hierarchies were still able to achieve amazing things.
But it’s not like they were making cars and computers, this is a drainage system. It’s very impressive for stone age people, but they are still stone age people.
