Tell me where this shows up in the process of watching a YouTube video. On a fresh device I can navigate to their page, select a video, and watch it. Never in that chain of events is this agreed upon.

Even if it's not binding, it illustrates what Google intends to do (stop providing the service via an anti-adblocker script) if you do not follow their TOS.
I want Google to pay my rent for the next decade, and Sundar has to offer a naked lapdance at the Pink Poodle every time they send me an ad I did not explicitly request to be shown.
Yes. They have complete discretion over what 'list of "things" and their URLs required to render a page' they decide to send any particular user agent (modulo copyright infringement, hate speech laws, etc.). There is no requirement that HTTP connections to 'youtube.com' should receive video data; or even HTML; or even that anything's listening on that port.
It doesn't matter what Google intends to do. Only what I do in response. TOS are not legally binding, they're a bunch of crap.
Contracts are only valid if signed.
