That's probably due to the 15 odd years of a lack of micropayments on the web, though. I'd pay $2 monthly for every one of the (very few, maybe 15-20) sites that I visit in return for privacy guarantees and no irrelevant advertising.
Unfortunately it's difficult to pull off a model where users can pay to turn off ads because it drastically reduces the per-user value of the remaining ad impressions.
