I think you have to be relatively nice to live sociably in stateless communal societies. Either that or have given up a lot of the individualism we nowadays take for granted. I think people used to living in big cities and within a state would not have developed the characteristics needed for living in a cooperative, communal society. It would require much adjustment or education or something even if it is natural for humans. It is difficult to know what is ideal - when I watch lovely program Tribe (amazing cool program where man visits cool tribes) it always strikes me and horrifies me seeing how insular and restricted the people's lives are and how narrow minded they are. Not all of them, of course, but it does make me think eek do we need particular world views and mindsets to be able to live in particular conditions and types of society, wah. And if so, who does the educating and who wants what and would people really agree and cooperate with one another?
I still think Kropotkin-style communities would be lovely, though. With nice libraries.
