An "ideal" society is a catch 22. It's impossible because what is ideal for one is not for another.

An ideal society for Fidel Castro was him in charge and the rest of his people living in poverty. Ideal is subjective.
There are as many worlds as there are minds.

I suppose an ideal society in a general sense would be one in which people could choose freedom and live as they desire, which is only possible through decentralization. No one person should play God and decide how others should live, but this is always the case as long as this is possible. it's human nature to be imperialist.

This is why it's important to support truly decentralized projects. That can which be found on https://defiprime.com/, https://www.virieproject.com/, for ex.
