From an advertiser perspective it is much nicer to use Google Shopping than the old days of attempting to use the regular text adwords to advertise products. Also better for customers on the regular search results page to find products with the shopping listings . There was a time when Google Shopping was both free and paid listings which was probably a better balance. Even if it still was like this I think having people submit product feeds still leads to much better results than just scraping.
