I was recently reminded of the admiration that some people voice for the Iroquois Confederacy as an example of society governed along more just, humane lines. On one hand, maybe there's idealization and whitewashing going on there. On the other hand, it's a big example of a gripe I have with how I see "utopia" discussed as it often is. People will criticize utopia as the notion of a "perfect" society, and yet end up coming off as dismissing any proposed social system more equal and less bureaucratic than current liberal democracy as pie-in-the-sky impossibility. I think talking about it in such a way... I don't know, lacks enough anthropological breadth, doesn't see that many different social norms and cultures have existed throughout history, and some could in their example give us hope in the posssibility of a world that is "utopian" by our standards.
Anyways, I always have more learning to do if I want to develop a more worldly understanding of politics. The future books on my list most relevant to me rethinking how I approach utopian anarchist politics are probably Communal Luxury by Kristin Ross, Seeing Like a State by James C. Scott, and Pastoralists: Equality, Hierarchy, and the State by Salzman
