I for one
would pay YouTube for an ad-free, smooth and offline-cacheable experience. At least now, that I have spare cash.
There is a rarely discussed topic of access for people who don't have funds or means to obtain it - like myself 10 years ago. It's tangential to ad blocking discussion, but a reason why I'm not sure if a pay-per-view Internet would be a good idea in general.
Oh, and if it helps me look better - I'm not really "ad blocking" per se, I'm doing responsive administration of my secondary OS (i.e. the browser) resources by using uMatrix, which makes me put some up-front decisionmaking work about which requests are or are not allowed on any page I visit ;). But it's fun, and I get to see how more and more insane the web is becoming :).
