I mean, it turns out that if we all specialize in one type of labor or another we each become significantly more productive than if we all tried to provide for ourselves as individuals or even small collectives. If we use money as a rough way of storing the value of our labor, we can use that layer of abstraction to trade labor with each other at impersonal scales, benefitting even further from specialization and organization.
I, for one, am glad someone else has gotten super good at growing food and building shelter so that I can concentrate on other things as I desire. I could even become a farmer, if I wanted!
