Well, this is a tribe, a chiefdom. It works, because the community developed around the chief and several "big man". The community culture is established, that is why,  most people are against changing it by vote because it would lead to newcomers trying to change a culture many people are happy  to live in.

I think there is nothing wrong with a tight knit community, on the contrary. Change can and WILL occur, just because psychedelics promote change. But the people will change together,  they won't be dominated by numbers.That's what partnership is all about.
