If you have ever worked with the public, remember: the public will be part of your politically utopic community.
All the mommy bloggers, all the brosephs, all the every single customer or client or other person you have dealt with who you wanted to fucking strangle, or at least wanted to be allowed one of those amazing moments of Put Down that viral reddit posts are made of, every single frustrating as fuck human: they will be part of your post-capitalist utopia.
They will not wake up, the morning of the revolution, and suddenly become different people. Your choices will be to line them all up against a wall and shoot them . . . .or figure out how to live with them in your community. (And multiple revolutions in the past hundred years have tried that whole "line them up and shoot them" thing, tried it REAL HARD, and it didn't work out great for them either.)
The more de-industrial, de-urbanized, de-impersonal, whatever, your ideal society is? The more it will involve having to work, and work well, and work effectively and without interpersonal violence (physical or social) against people who irritate the fuck out of you.
And no, we never really had any Neat Trick to make that easier in the past. What we most often had was survival pressure so intense that the threat of being ostracized (or having the group turn on you) was enough to force resolutions that nobody was really happy with, or that left an unspoken wound to fester for generations, or to offer up a scapegoat to vent the community's violence on and then pretend to move on, or . . . .
If you want a cooperative, non-violent, non-coercive community, and especially if you want that to be the norm, you end up having to learn to work collaboratively and productively with the person who irritates and frustrates and upsets you most in the ENTIRE world. And if you can't picture doing that, then maybe it's time for some self-reflection about how you really want the world to work, and what you're capable of contributing to that.
