You got one thing terribly wrong in your argumentation. Ad blockers are NOT the fault of YouTube per se.
I don't see ads on YouTube because of my ABP, but I didn't install it to block ads on YouTube, that was just a nice side effect or collateral damage or however you want to call it. I installed it to block ads on other sites that were irritating me, the risk of drive-by malware infections, and the general lack of interest in whatever they were trying to sell. It is the whole of the Internet that made me install an ad blocker.
Maybe a few people installed ABP or equivalent specifically because of YouTube, for most I think it's not like that. By now I install ABP on a new system as a matter of course. Even if the Internet at large would do away with ads suddenly, I wouldn't notice the difference, and I would still keep ABP running. Same for the pop-up blocker of Firefox. For years I haven't seen pop-ups or pop-unders (except that really persistent one from TripAdvisor), I don't know if they're still being used, and I'm not about to try it out either as the blocker doesn't seem to be getting in the way of anything.
Now only if there were a proper ad blocker for Android phones (haven't found one)... I rarely use my phone for browsing but there are some really really annoying ads going around apps (black/white flashing and so). It's those that drive me into spending the time and effort of installing blockers.
