Money exists in other forms other names money is effort and effort is time, your time. Hunter-gatherer societies would have an equivalent of money not literally notes and coins but trading their effort and time. It is literally a society, people gather in a group for mutual advantage. The advantage being I don't want to personally make, build, do everything to survive so you trade skills which is effort and time which is essentially money.
