So you really like a channel, and I am assuming not all are poor, that is a big difference. I wonder what the friction is here. (As someone who is very aware of the effort some creators put in)
This task falls on the creators, not the viewers. There are already several options such as sponsorship, merchandise, patreon, asking for donations, et cetera.
18% of revenue being sourced from YouTube ads doesn't sound like much, but extrapolated from $4.6M over 9 months to a year is ~6M in ad revenue, out of a total of >$33M from all sources. It's not as simple as "flicking a switch" to replace that revenue with $3M of extra in-video sponsorships (those are already being bid on at market price, and they're in as many places in the video as the viewers will handle) and/or $3M of extra merchandise revenue, for example.
And no creator does good by asking for direct donations. Only patreon/a way to pay for early access to content does anything for revenue, and this is not scalable since the vast majority of <every> channel's viewers only watch it when it's conveniently shown to them via their recommended videos/subscriptions tab.

There is no real community on YouTube, you're there to watch videos, not making friends. And video hosting is flexible, one video can be hosted on different places.
Sure, YouTube was very smart that they changed how the home page worked, so now people rely on YouTube to explore and discover video for them, BUT it won't change the fact that you're still there to watch videos.
Now I through about it, maybe that's why YouTube is so careful about their public relationships.
Plus, the recommendations engine itself is a limitation. I been using YouTube for years before knowing the existence of YouTubers such as Casey Neistat, Mr Beast and SomeOrdinaryGamers. Even through they are popular and talked the topic that I'm interested in, YouTube never pushed them to me, instead, I manually discovered them through the trending page, what an irony.
