Well you can't be average to run a good peertube instance. I was thinking more of people like Joe Rogan and Linus Tech Tips. People who've built a company around their content creation hobby and are capable of paying for ops and potentially seed boxes if needed.
It wouldn't be hard to host, but you'd have to be confident in your service provider or consultant.
Of course I doubt Linus would ever be censored by Youtube, he was just an example.
Regarding the seeding I was thinking that you could put a few dollars into seed boxes to bolster some older or rarely watched videos.
