Can you still extrapolate from this that the tipping model is even anywhere near a threat to Google's ad based business model that they should be incorporating it? And is it even an apples to apples comparison? Many creators don't use Patreon in spite of or to replace ads, they use it as a supplement.
Moreover, just because something is technically simple to integrate, doesn't automatically make it the correct business decision to do so.

No, but we can extrapolate from twitch, and guess that it probably would be.

Because it is a third party site, there is no such option. It would be trivial to incorporate an ad-free experience for donations/subscriptions similar to how twitch does.
This exists, already competes with Twitch, and is part of an even bigger portfolio of media services from Google. You're arguing for Google to do something they have been doing for years.

You're vastly overestimating what people will actually pay for and underestimating how big and critical the ads industry is.
