And that’s about as detailed as the plans ever get. How exactly are the non-hierarchical democratic councils laid out, and how are they any different from normal representative government/state? At best they describe representative democracy with generous recall rules, at worst I’ve heard “all rules are repressive, no further explanation will be provided”. And that’s not even getting into the economic questions, if this is going to be a non-market system.
Only one way to find out if it will work.
I’ve seen pretty much the same argument from ancaps about their self-contained Gordian knot of contracts that never collapses. It’s true, weird ideas that sound impractical work sometimes, so I can’t prove it wouldn’t, but I’m not holding my breath.
As for those couple examples, I suspect they work in a very different way from the theory, although again I can’t prove it. Republican Spain never really approached the Anarchist ideal, at least, and that’s the one there’s good information on.
