Yeah that's beyond my claims though. I'm only saying that they're totally fungible and things getting done don't depend that much on a specific individual.
Mmm as far as experimentation, the closest I can think of on a large scale (besides anarchist groups which never had leaders) is that in Europe when a government can't be formed, they can operate without any official leadership even though there's a caretaker government (usually the previous one, who don't have a mandate anymore) but that's kind of formal. Big cooperatives usually elect leaders, so they still have them even though they're elected and can be recalled.
