If you are convinced that one needs a king in order to make food, then we will always need a king (in more modern forms of presidents, parliaments, or whatever aristocratic structure). Because we will never be free of material needs and always be prone to physical violence.
Wow. What you smoking?
If you believe that one day we will be free of material needs and will not be prone to violence, then I think the guy smoking heavily is on the other side of the line
I still need a house, I still need food, I still need a lot of material stuff, and I can still be beaten up, tortured, and killed. I don't think that this kind of thing will disappear in any near future, on the contrary.
