Yes. Even a communal style of life works at small scales. But not at civilization scale. This is accepted and studied. And in particular the studies focus on the effects of the size of the group. As the groups grow larger the free riders appear. But I think what’s worse is that even if they didn’t have that problem they would still face the economic calculation problem and end up producing the wrong things instead.
I don’t think it’s an inevitable result. As we get better at handling complex systems we might have a chance at a more efficient planned economy (that would still have issues but so does capitalism) we are not there yet. I do think that capitalism is the best system we can currently use. It doesn’t mean it’s not flawed
I don’t think that my opinion is about how relevant I think the economic calculation problem is or worker productivity. It’s the famines that follow its implementation that i find “relevant”.
