Ads can have both persuasive (propaganda) and informative functions.

Informative ads make the market more efficient. Persuasive ads actively make the market less efficient.

Most ads in the US in 2023 seem to be persuasive.

Perhaps the ad industry would become more useful (and smaller) if we managed to effectively regulate it to significantly reduce the persuasive bits.

I think that most people would support this if you explained it right - from the free-market perspective, this would give you a better market.
