I thought that the "Barter theory" was mostly forgotten by now. This was an hypothesis proposed as early as Adam Smith. However, it appears now that most "primitive" societies did not use barter but rather the sharing and gifting of resources. This is the currently favoured hypothesis: the Sharing Economy.
favored by who? why can't I find a single reference to "early societies were sharing economies". Also that doesn't seem to scale well since. I share with my friends, family and neighbors, but none of those people can make me a PS5
