I don't have the proof but I'm guessing that this is provably wrong. Without advertising in some existance it would be nearly impossible to start a business which means everyone would be peasants farming for subsistence living. I think the problem is that the propose of ads has become divorced from product. The issue is poor regulation not the existence of ads.

Think about it, how as a small or competitive business owner would you get people to buy your soda vs coke/pepsi without advertising in some way? The issue is that coke/pepsi know they have a simple product so they blast ads not to sell their product but to adversarially drown out competitors before they can exist. Tons of advertising has counter agenda purposes like this rather than selling a product, its propaganda not advertisement. There are probably tons of unenforced laws already about this but IANAL.
