Because YouTube wants you to not think, but just provide content and shut up.
Peertube (libre softwares in generals) requires to think about things and to make choices by yourself. It doesn’t try to be more than what it is = a tool for easily host videos.
Peertube isn’t a platform.
Because anyone with a computer can host a peertube instance. Therefore is you want your videos on peertube it will cost you nothing more than what you already have : a computer running and an internet access.
The only real barrier is having the time and the knowledge to set it up.
Peertube is tech solution to host video, not a way to make money with videos. Monetisation can be done with peertube, but it’s up to creators to set it up.
Well if you don’t know how to operate a car, you should not drive. If you don’t know the basics, you won’t be able to do small repairs yourself. If you don’t know nothing about cars at all, you will likely have to paid more than someone with more knowledge to obtain the same result. Ask any cab if he just pays and doesn’t know anything about cars.
If you’re a video creator who wants to make money with your videos, you should be knowledgeable about monetisation and video making. Don’t be lazy, it’s just your job.
