The problem (as matrix people found out the hard way) is some media & content is very illegal. Most individuals really don’t want even the chance of being exposed to CSAM or gore, and neither do server operators want the chance of that being shared from their server or written to their disk when that can result in police at the door. You need default-on moderation that is very powerful, and end users should never be distributing media they don’t want to. This pushes towards centralisation of nodes run by experts, and heavily punishes true P2P models.
