I think this is a spot where YouTube fails to give a "fully valid" option as a platform. As a user right now I can have YouTube Premium, be a Patreon, and leave a Super Thanks on a video but still get served a sponsored segment. At the same time on the creator side I have no way to target YouTube Premium users or people paying directly to the channel with different content while keeping it as the same posting on the same platform (i.e. all as one video post on YouTube). As a result, no matter how you slice it, there is no way to have things be "right" even given ideal and fully willing creators and viewers.

This leaves the only realistic way for a channel to make reasonable money to be via ads and sponsored segments targeting the majority of non paying users at the expense of the rest.
