Honestly, I'd take a slightly different tack: ban all advertising except that which focuses on product features (like a lot of old-timey ads did), and then have strong enforcement of penalties for false advertising. Then limit innovation in delivery to places where it's both not intrusive and already established (e.g. media publications, etc). The manipulation and excessive proliferation has to stop, but I don't think there's anything inherently wrong with a business being able to reach out to tell people about what they're selling. There just needs to be strong regulation to speak for other interests in society.
