I have a Plex/Radarr/Sonarr setup on my home server. I've made a landing page so it's extra easy for my parents and friends to add media.

It's been really wonderful, everyone knows everyone by one degree of separation (me) and are adding to the library like a sort of group project. You can just hop on and see a somewhat currated library in the sense that someone you'll probably run into IRL thought this was worth watching.

So just to add to your point, you can't get this with a streaming service.
