It's actually amazing that Google has let Patreon eat its lunch on this front, the latter becoming the predominant platform for direct monetization while YouTube continues playing the chump's game of seeing how much advertising they can inflict on users before they revolt.
[edit] I'm well aware of YouTube Premium, but Google's insistence on bundling it exclusively with YouTube Music greatly limits its appeal. If they offered a standalone subscription (as they are piloting in some European markets), they could probably expand their subscriber base by a significant factor.
Put another way, if Netflix were only available as part of a bundle with a cable subscription, do you imagine they'd have more or fewer subscribers than they do right now?
