I don't know man, I visit sometimes hundreds of sites a day, if I had to pay even $1/day to visit a site, I'd be paying hundreds of dollars a day. I'd rather view an ad. I already pay out the ass for internet. I don't need to pay to view content on the internet too.
You could pay for some websites and be limited by a paywall for the others.
And the content on the internet has nothing to do with your ISP so I have somme difficulty understanding your argument "I don't need to pay to view content on the internet too.".
Meaning, a paywall everywhere is not a smart thing to do. Yes I know content is independent of ISP, that's why I accept ads. Because that's how content producers afford to give you content without charging you.
