Humans organize in manners most efficient for their conditions
That's ridiculous. Communism is way more efficient for our current level of development than capitalism, yet we're doing capitalism. I don't want to hear you argue capitalism is most efficient in the 21st century, it's not. We've got homelessness, poverty, climate change, genocide, planned obsolescence.... Capitalism stinks. Quit defending it.
Instead of fumbling around in the dark with only two centuries of failed attempts, you should learn from the millennia of success that has already been achieved.
