I don't think there would be a whole lot of need for delegation in this system - but I don't necessarily see a need to do away with it.

Since stake can never be bought or sold, there is no possible way for bad actors to take over the system, and there will be various methods to limit the overall gap between a first-time user and someone who's been there doing great stuff for years.

There will be zero possibility of one person's vote being worth millions, while others are worth 0 or 1.
