What business model do you envision for the web, then? Sure, my own websites are ad-free, but they're purely hobby projects and I don't feel like the (small?) income would be worth the personal discomfort of "selling out". For those who can't afford to develop and host good content for free, what's the solution?
I think this is the biggest problem in the Internet sphere right now. It has been in the backs of everyone's mind for 20 years, but with no other solution available, the Internet has been financed 100% by ads.
I often dream of a world where x% of my ISP bill is paid out in micropayments to the content providers (think about it, we pay ISPs for infrastructure that would be worthless without content, and they get all the cont for free). But that ignores actual bits, so in the end I wish there was a protocol for me to pay for the content I want, and in exchange the provider would give me ad-free content. Now imagine I could choose (or have a browser setting) what level of payment vs. ads I want on each website.
I realize it can't be that simple, the economics of the Internet (from end to end) are much more complicated.
