Let’s suppose that this interpretation of finds by contemporary archaeologists is correct. There is quite a clear distinction to be made between exchanges between otherwise isolated communities that didn’t have a burning need for trade (which they btw absolutely didn’t, there is the concept of primitive communism that is rather well established from observations of recent hunter-gatherer societies) and trade as the dominant social force.
Trading goes back to prehistory, as as archeologists will tell you.
