I get the history as to why we got to our current economic situations, but no one is arguing for a system that casts off current economic issues that are pushing humanity towards destruction. I’m not saying this can happen over night or even within our current life time, but it’s obvious that capitalism and even socialism has reached the end of their usefulness.
It’s pretty hard to imagine a way for groups of people with varying goals and interests to operate without some form of value exchange. This can either be barter, or some form of currency. Our specific kind of extractive capitalism based on creating endless cycles of debt and credit can certainly be replaced with any number of alternatives, but the idea of money itself is just too basic and useful to humans, imo.
