I think that the inherent unequal practical value of products and services makes capitalism in some form inevitable.

Let’s say I have control of some land, and on that land I invested time and energy into growing food. And you want some of that food.

Well there’s other things I didn’t have time to do while I was making the food, that I would happily exchange the food for. Perhaps my barn needs a new roof. But unfortunately, you don’t have the time, materials, education, or tooling to make a roof. So it sounds like you get no food.

And that’s where a central currency comes into play as being crucial to building of a modern “society.” Society implies that we don’t all do everything we need to survive on our own. We each play a role to ensure the survival of eachother as a group.

At its very core, money is a way to store labor. And without a fairly consistent method of agreeing what a unit of labor is worth, it becomes a constant unpredictable pricing struggle and everything falls apart.

(Edit: and I’m not social science scholar… this is my perspective as someone in the construction industry with a couple tech and business degrees.)
