Interesting points. If I were designing from scratch, I would probably use a Peertube/Mastodon type federated system. Each host would responsible for the videos they host - meaning they would have incentive to limit videos uploaded to any given host to an amount they could handle, or only allow trusted uploaders to their host. Then you would have the federation so that you could allow hosts that you didn't have issues with, while blocking those you did. Eventually, there would evolve safe/block lists - like with email and adblockers - so it wouldn't even require that much effort on the parts of those running the hosts.
