It requires profit maximising ruggedly individualist property holders, and that is not the case in a tribal setting. As to store of value setting, again it is not applicable in any tribal setting. I understand that cattle became a 'store of value', but that is true of herder society , not hunter gatherer. In herder society we have the rise of private property, and hereditary ownership passed through the linage of the father, (or patriarchy). That is the more significant prerequisite that must occur before any type of barter can occur. Private property had to exist first before there can be any type of barter. As to such a society "agreeing" that so many shells or lumps of metal are equal to so many cows, that is nonsense. Money was invented by the state, for enforcement of penalties.
