Exactly my thought. But it definitely wouldn't get mass adoption which is good because mass-market content websites are questionable in terms of user experience (they also need to cover content creating costs by popups/ads/pushes). One thing, though, ad based search engines lift ad based websites because they can sell ad on a second end. Maybe we'll see advent of specialised paid search engines SaaSs with authentic and independent content authors like professional blogs.
