I like this idea in theory, but I think it would be easy for bad-faith actors to game the system. Expertise can be faked and reputation can be manipulated. Governments or other powerful/wealthy organizations could easily fund a large effort to shift agreement metrics toward their preferred narrative. We know Russia and China already have whole farms of people on social media trying to skew narratives and perceptions. Hell, I could see a tech-savvy individual distributing a software package to like-minded (or gullible) people in order to effectively automate the process of skewing the agreement metrics.
