Do you know what happen when advertising is banned? It would go underground -- product placement, contest, merchandises, and so on. Advertising existed as soon as commerce became a thing, probably thousand years ago. It can't be banned. I wouldn't vote for that.
Regulation, on the other hand, is fine. How? I don't know.
> It can't be banned
Sure it can. I don't see how being old makes it immune.
