What kind of content creators do you imagine needing this?

Real talk, nobody at YouTube is editing your uploaded videos.

Since you need to own a website to publish, can't you just put a bittorrent magnet link on there? Or IPFS or other flavor-of-the-month.

I'm struggling to imagine your blockchain not being largely composed of pirated movies, child porn, and Nazis. Everyone else is served well-enough by easier alternatives.
