Haven't watched the video, probably won't. I don't get what the mystery is to be honest. Humans have always been playful and creative beings. Add complex societies, strict hierarchies and compulsion to the mix and a pyramid isn't all that far fetched or even surprising.
In my mind the popularity of modern ideas like homo economicus and evolutionary psychology have done more damage than good. Humans are not and have never been strictly rational actors, few if any animals are. People do stupid shit for the sake of it all the time.
