No they wouldn't. There are numerous people who choose not to go down the video for income route, myself being one of them. I'm a second tier partner who rarely monetizes videos and if I do it's only so the video gets more views, not for financial remuneration. Not everyone is motivated by cash.
'YouTube is a 13+ site, not an "adult" site. That means you should not be uploading content that isn't suitable for 13-year-olds.
If you do upload more adult content, you run the risk that it will be removed and your channel will receive a strike.'
It's quite curious that those who post 'answers' on this forum always seem to take what exists as the only way anything can be done. I had a similar experience when complaining about copyright strikes, which interestingly YT changed it's policy on shortly after. I've been here for more than 6 years, I know exactly how things have worked, or failed to work. Just stating the status quo is not helpful.
Let me give you an example of how this could work. I don't know what country you're in but here in the UK we have a watershed on TV of 9pm. After that more adult themes can be explored. I'm not suggesting 'adult' means porn (which I suspect you're interpreting it as) but for grown ups who are able to discern, talk about adult topics with other adults after the children have gone to bed, though in this case it would simply be unavailable to them at any time. We are all perfectly capable of behaving in rational ways and not harming minors without only ever presenting or doing things which they could accept.
