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 line is clear: is money being exchanged in order to promote a product? That's advertising.
Someone I know mentioning a product because they want to recommend it to me? Not advertising.
Giving out "free" samples? Presumably someone is being paid to do that, so advertising.
We can later quibble about edge cases and how to handle someone putting up a sign for their business. Many countries have regulations about visual noise, so that should be considered as well.
But it's pretty easy to distinguish advertising that seeks to manipulate, and putting a stop to that. Hell, we could start by surfacing the dark data broker market and banning it altogether. That alone should remove the most egregious cases of privacy abuse.
Studio Ghibli made ~$220m on Spirited Away. What if they made $2.2T, is the quality going to go up, or down? And, would there be less ads, if no one made even $2.2 on them?
What's the connection between adverts and the amount of money Ghibli made on their best-loved movie?
Hmm, maybe none, maybe you're using Ghibli as a metaphor for products that make money through adverts. And maybe the implied answer to the next question is that their next movie, The Cat Returns, would have been higher quality if they had made even more money on Spirited Away. So what you could be saying is that crippling the ad industry would lead to lower quality products, without even much reducing the number of (less effective) adverts that get made.
That's one way to read what you said, but I feel like I got it wrong.
People getting paid to do things do worse than otherwise[1]. They do better when not paid. The quality of work often gets worse when they get more. It's well established. As counterintuitive as sometimes it seem to be.
What I'm essentially saying is, if you think people are right now getting paid to do something bad to the society(e.g. ads), you might want to keep them hooked and tied to the money and not to something else, like advertising for its own sake.
Fear the work of unpaid ad execs! They won't stop making adverts, it's what they live for, money or no money! The adverts will continue to be made, but now they will be made for love, and they will be extremely high quality! And if you think ordinary adverts are bad, wait until you see what adverts are like when they come from the heart!
