Kropotkin used Europe constructing its international railways as an example in Mutual Aid. Basically one party sends a delegate with a proposal, the second party either accepts it or revises it and sends it back. And back and forth until a consensus is reached. I want to emphasize before someone says “that wouldn’t work.” Thats how it works now, except the organizations rn are hierarchical and profit-driven, while we want them horizontally organized and need-driven.
