That's not the point. The more ads there are at the top, the more google is effectively allowing you to pay for good ranking. This violates a lot of the search neutrality that makes google so useful. I think of it like Yelp. I want the services other people like, that are relevant in some unbiased sense, not the ones that paid to get there. The harder google makes it to find unbiased info, the worse the service.
