even assuming 100% buy-in for content providers for google pass as an ad replacement, it doesn't replace all the use cases of a decent ad-blocker (like ublock origin). For me, I block newrelic, google analytics, segment, and a whole bunch of non-advertising related sites that slow down the web. Doing this more than halves the load time and download requirements of just about any major site.

I absolutely agree, but you have to acknowledge that these are mostly things that only highly technical people care about. In the Torrent analogy, this would be like saying you like your music in lossless FLAC format, or DRM-free.
