Check out webpass.io. It's designed to work alongside your adblocker, as a way to financially support websites via a subscription. Those sites that receive money from the subscription have to voluntarily remove their ads, and your adblocker will continue to block ads on all other sites.
Check out our service Webpass.io, which is a step towards what you're asking for, and have a look at our privacy policy if you please. Tracking is one of my greatest concerns with advertising.
As you say, 'damn few' do, but some do. Some offer the option to subscribe, or pay a once off fee to remove those ads. My concerns in those cases are that it means remembering a separate account for each such website, signing into those websites each time my session expires in order to remove the ads, and paying a significant sum of money if I do it on too many sites.
That's why I've started webpass.io, a service that offers websites an easy way to offer the option to pay for content, but that avoids these extra kinds of concerns.
