I found your ideas, about tribal business, from Beyond Civilization interesting, but the food is still under lock and key. How do tribal businesses remove the food from lock and key?
I live in Nicaragua, and I would say that 50% of the people here belong to tribal businesses exactly as you describe them. Still, a few rich manage to maintain strict hierarchy, and food under lock and key.
From the evidence here, it doesn´t seem that purely tribal business “works”(domination system evolves to suck it in). It also occurs to me that this idea of tribal business has forgotten many other aspects which made tribes “work.”
