I don't know but I suspect my definition of capitalism and yours are different. From my perspective if I have a goat, and that goat has kids, and I trade you one for some seeds we have a functioning, but tiny, instance of capitalism.
I used my resources to produce more resources, you did too, and we exchanged in a way we both considered to be in our best interest (Or we wouldn't have done it).
If I'm way off base I'd love to hear.
