It’s not, actually. The majority of human history is neither humans fending for themselves, nor submitting to wage slavery. Humans are collaborative, social beings. Even the nuclear family is an aberration on our otherwise multi generational and communal shared history.
Yeah, all human societies worked together on large communal projects and would make things and exchange it with others through barter. We still do those things fairly regularly.
Sure, it wouldn’t work for a large an complex project like going to the moon, but that wasn’t done by a capitalist company either.
Barter, as was taught to me at least, is mostly a myth. Barter certainly existed, but we have no evidence to support barter as the primary method of trade in any period of history. It primarily existed, where it did exist, as a way for people from disparate cultures to trade, within communities barter was nearly non existent, and most things were done in a sort of social credit system for much of history.

Here’s a source for you. It will help your argument. As someone who has actually studied it, I agree with your hypothesis.
