I doubt YouTube would ever have been successful if it had required this level of explanation.
For someone who has never used YouTube as a content creator, a "Getting Started" guide for PeerTube would actually be quite short.
If you want the equivalent to Youtube, take a look at something like https://framatube.org/
Case in point: "Recipe: Medium-Boiled Eggs" https://medium.com/@corey_nelson/recipe-medium-boiled-eggs-7...
;D
The only thing I got from reading this write up is that it will be pretty easy for someone to create their own instance and throw ads on someone else's content.
That long tail is what drives growth for these platforms anyways.
Plenty of huge YouTubers don't use any YT ads at all.
Even for millions of views on a video its typically less than $100
