Sure, you can create an open, free-for-all curation guild under this system, but I can bet not a single whale will donate their voting power willy nilly. They'd only delegate it to a trusted curation guild. You don't have a trusted curation guild if it's free for all, everyone voting how and as they please. So there will need to be people managing the guild, who decide whether a curator is given the permission to vote on their behalf.

Everything written in this post is a specification proposal for a system. Of course, this would need to be coded.
