> Capitalism appears to be the emergent system of many independent agents engaging in voluntary trades

Not correct - in Ancient Egypt, all the land belonged to the people through the Pharaoh (great house), and they both had the independent agency to do voluntary trade with they wanted with part of the produce and lacked that agency as they had to pay some share from the land assigned to them as taxes.

> I don't see a whole lot of e.g. Set or Horus worshippers these days, for example.

Except the modern cultural paradigms originate from that very Ancient Egypt. From the monogamic marriage paradigm to higher education. And those Set, Horus etc have been meshed into the 'one god' concept as its aspects, and then that one god and practically every major thing in the Ancient Egyptian religion were used to create the modern religions. From 'weighing of the heart against a feather' for judging the goodness of the recently deceased in the afterlife to the very concept of after-life judgment, most religious belief traits come from Ancient Egyptian religion.
