There are plenty of known religions that share no significant similarity with Sumerian beliefs, ie basically every First Nation/Native American religious system. People have been in the Americas longer than Sumer existed.
And thats just stuff I'm even vaugely familiar with. I'd wager 0% of Subsaharan African religions, aborigional, and probably most Asian religious beliefs don't have any Sumerian influence.
Are we just gonna ignore the fact that the whole critique of centralization is that its inefficient, ineffective, and unresponsive to peoples needs?
Like as capitalism is becoming more monopolistic, its becoming increasingly bad at delivering goods that people actually want and just becomes better at supressing and controling them. You know the same critisism thats pointed at autoritarian communism.
I don't think this is the W you think it is.
