Even if you implemented this how are you going to replace the ad money and the viewers?
However, you could make money like many professional youtubers: sponsorships for companies. Getting a sponsorship requires a certain amount of fame and viewers in the first place, though. It'd be near impossible to start a Youtube-like career, but for existing Youtubers who can use this system as a secondary/alternative video host, the problem wouldn't be so big.
ads can be implemented but I'm not sure why you are saying that you couldn't get viewers...
