Well that's kind of the problem isn't it? Sure, you can criminalise outright lying (and perhaps we could do better at that), but things get a lot murkier as soon as you go any further.
Besides, most of the manipulation of advertising isn't about explicitly misinforming people, it's about associations and familiarity. You can't ban an advert saying "Coca cola exists", but it's still going to mean people end up choosing it over potentially better options.
