A pure democracy doesn't work in a community of so many people. Maybe we should do the same for America, and just have everyone vote on all the laws before they're passed.
You have to have someone with final executive say at the top. We already have a "board" of people making WP decisions. As you know, anyone can join in on this in the wp-dev chats.
Until someone can explain why the current system doesn't work, I see no reason to entertain this idea.
For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
