That does not prove your point at all. It simply says pure and simple barter economies- have never been described. Sine more or less money show up around the time of recorded history, no one described much mushh before money.
And generally, a Book as a cite is not the best. Something we can all check to see if the quote is out of context.
Certainly a gift system works among a close knit group of people- a family, an extended family etc- but to cal that “an economy” is stretching that word out of shape… But how about once the village gets big enuf to have an economy? or when you start trading with other villages? Maybe they have flint, and you have ochre. You have to trade. Thats when barter steps in, that when you have a real economy, instead of just a family group.
