Here's another angle: a LOT of common people out there don't even bother blocking ads, let alone even thinking about the possibility that it's possible to block ads without using Youtube Premium. They either:

a) Live with ads, thinking that's the norm or not giving it much thought, or, b) Subscribe to Youtube Premium without considering the possibility of ways around it.

So, realistically speaking, the probability of everyone starting to use Vance overnight is almost zero.

I also used to feel the same: why can't people just use adblockers!? Then I realized that me and the type of people I normally interact with != the general public, atleast in terms of tech-savviness and/or curiousity.
