You're completely ignoring the fact that the majority of people do not expect a search result ranking to be influenced by bidding. Yes it happens, but unless the item is labeled as an ad, most people will infer value that does not exist. And this is wrong. The only reason they appear in the search is so that they do not look like ads. There's plenty of places to advertise and the best for the consumer is for transparency to exist in the first place.
