The courts already distinguish "commercial speech" as a class of speech. Would we prevent all forms of commercial speech? What about a waiter asking you "would you like to try a rosé with that dish? It pairs very well together." Is that "advertising" that would need to be outlawed?
What about giving out free samples? Is that advertising, and thus should be illegal?
What about putting a sign up on your business that says the business name? Is that advertising?
I hate advertising and propaganda. But the hard part IMO is drawing the line. Where's the line?
The internet is supposed to be an information retrieval tool. Advertising’s whole goal is to stand between you and the information you actually want. And it does so by trying to anticipate instead of the thing you want, the thing you are most willing to buy next, whether that’s actual products with money or propaganda. Whereas an ad in a magazine about computers offers me relevant ads for products about computers. And if you read old ad copy a lot of it is a serious effort to try and convince you to buy their product. From some kind of argument for it. Instead of simply using statistics and data to predict what you will buy next. So this required the product to actually deliver something to justify the effort to advertise it.
