I applaud your efforts, but your post-ego world requires rational humans, and you have well explained that 'reason's got nuthin to do with it'. Even if we could devise a system employing cooperative, anti-ego feedback rule mechanisms to combine the individuals' tiny Executive functions and overcoming our pigeon brains, bullies don't follow the rules. Somewhere in the post ego system, there needs to be an anti-bully(anti-colonialism) power (corruptible corruption), and someone has to have the ego to weild it. Maybe it's an illusion that we can come up with something substantial that is better than the ethereal Invisible Hand Job, but as we face the collapse of atmospheric stability, it all seems like musturbation.
