I've been a Twitch viewer for years now and have been following streamers who have at least *some* integrity and values and who - time to time - openly talks about them.
Thus I know, it's not only possible to keep assholes out of your chat, so people can properly communicate with you and each other, but many people not only enjoys, but are *eager* to listen about integrity, values or philosophy from the streamer.
If that's only because they see the popular streamer as a celebrity / authority / role model - I don't know.
Is there enough viewers like that, who could secure your living? I don't know that either. But Stefan didn't know too, until he tried.
And I don't know the demography of the viewers, but at least some of the viewers have an actual jobs, that allows them to have a stream opened in the second monitor / window - and it's kind of like a radio for them. It can also help somebody to socially interact with people this way, share their troubles, maybe get some empathy or advice even - from the chat or streamer himself - or of course just relax and survive some stressful episode of their life.
It can be a very addicting way to procrastinate of course - but as with Stefan's podcasts, it can be a useful way to procrastinate, which could actually help you - depending on the streamer and his content.
Anyway, I would welcome to play - and hopefully stream someday - with you guys.
