SepiaSeach will search a large number of instances for content. Not a bad start for peertube. But I do agree that it's hard to find good content there.
It’s not about monetisation. It’s about audience. Who is going to bother to host an instance and post to a platform where the most popular videos only get 100 views?
That’s not true. Check out the pinned post at !peertube@lemmy.wtf for a list of content creators. Also check out the home page of PeerTube.wtf that also has a list of content creators.
