I'm not sure I understand how providing a means to run your own server solves all these issues. Foremost in my mind is how you ensure competitive integrity when you can no longer trust all the servers. However, that's a bit beside the point.

The point I'm trying to make is that these things have been tried by one game or another, and there's good reasons why the "run your own server" model died for the most popular games. Ignoring that is, I think, discarding a lot of historical evidence and nuance against blanket "why don't they just do X" arguments.

If there's a better way, it won't be a return to the past. It will be something new that no one has thought of yet.
