For the years I ran the "One Page Dungeon Contest" (where people submit entries and win prizes other people have sponsored), I created a 2 person association with my wife. It's a way to limit financial liability, of course. That is often a more tangible benefit rather than the "let's all do the work and get together once a year and have some votes" which sounds more like work than freedom. But still, having the option of changing the leadership is something that works in a society where we can't all be hyper-individuals.
