I don't want a service that blocks ads for a price. I want a service without ads. If websites can't find a way to sustain themselves without ads, then they can die off for all I care. I can live without the content harvesters and the news reposters and all the other extraneous fluff out there. There will still be companies that sell services and advertise their own stuff on their websites, and there will still be people that pay for their own web hosting to put up content they are interested in.
If the pushback against ads becomes extreme, there will still be a web after natural selection has finished running amok.
I stopped using free web email, as one example, because of the ads. I now pay for email services from a company that does not run ads and does not track me around the web. There is no free version with ads. This is what I'm after.
I wouldn't mind something like CoinTent after the die-off though. Paying money in one place that would be distributed as I see fit adds value for me. I don't want to be followed around the web though, that's a deal-breaker. Let me select the websites my revenue goes to and with what weightings. Sites that impress me will get added, sites that disappoint me won't. Also, let me determine how much I wish to give. Do this for websites that don't post ads, and you've got a winner for me. I will gladly pay for a useful web, and advertisers can go extinct for all I care.
