Taxing or banning advertising alone would fix literally everything that is wrong with the web.
Taxing may be a good way to restore balance. Banning means goodbye online news, Google Search, Gmail, YouTube, Maps, Translate, ad-supported games, etc. -- basically everything we've become accustomed to having for free will want a monthly subscription.
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.
