I agree with this sentiment. However, I think advertising is necessary because what if you want to make a be candy bar? How will people know about it? The flashy wrapper you put it in? A fancy end cap store display? A billboard outside the shop you sell in? A television promotional? Is Steve jobs talking about iPhones an ad? Is bill gates talking about diseases an ad for Microsoft because they are intrinsically linked? There's no easy way to articulate what should and shouldn't be allowed.
This makes the argument that the need to convey product information is now fully accomplished by search engines, and advertising only adds harm / manipulation.
