I mean, you stated it pretty clearly yourself. How would a recommendation system rivaling YouTube's work in a decentralized fashion?

There's also the fact that people spend a lot of time, effort, and money making these videos. How would they get paid by a decentralized system?

I want to decentralize too, absolutely. But I'm at a loss as to how we'd accomplish it in a way that ultimately benefits society instead of making an inferior product.

Americans don't like sharing.
