A large swarm of satellites, forming an adjustable solar shade, sitting around L1 for Earth-Sun is likely the best approach we would have. The swarm wouldn't be in a geosynchronous orbit, though, but instead a heliosynchronous one.
Instead of focusing too much on all of the things that are currently wrong, could you please help paint a picture of what a future utopian society could look like?...
Realistically? Something a lot like what we currently have, but with everyone having access to prompt healthcare, living in comfort. A focus on community and cooperation being more dominant in the culture, rather than competition and comparison.
Exactly this. On Reddit, you would end up with stuff like r/TrueStarWars and such as a result of bad mods moderating badly — but those communities would have a harder time taking off due to the name being less searchable, and individuals needing to be "in the know" about why one sub has "true" out the front.
With everyone being able to take the same community name, just across different instances, there's a potential for a better, more competitive process to take place instead. It won't be perfect — @starwars is going to be in a much more immediately advantaged position than, say, @starwars — but in theory the playing field is closer to being level.
What would happen if we put a giant glass tinted dome over each city?

should we be worried about powers-moderators/users?
Power mods are one of the main problems with reddit. The same thing is already happening with Lemmy....
