I tend to think the answer is to go back to villages, albeit digital ones. Authentication only enforces that an account is accessed by the correct "user", but particularly in social media many users are bad actors of various stripes. The strongest account authentication in the world doesn't help with that.
So the question, I think, is how do we reclaim trust in a world where every kind of content can be convincingly faked? And I think the answer is by rebuilding trust between users such that we actually have reason to simply trust the users we're interacting with aren't lying to us (and that also goes for building trust in the platforms we use). In my mind, that means a shift to small federated and P2P communication since both of these enable both the users and the operators to build the network around existing real-world relationships. A federation network can still grow large, but it can do so through those relationships rather than giving institutional bad actors as easy of an entrance as anyone else.
But this causes other problems such as the emergence of insular cultural or social cliques imposing implicit preconditions for participation.
Isn't it rather brilliant that you can just ask questions of competent people in some subreddit without first becoming part of that particular social circle?
It could also reintroduce geographical exclusion based on the rather arbitrary birth lottery.
