Prohibitions tend to end badly.
I'd like to see a very high taxation on advertising, especially by class or scale.
The local sandwich shop, theatre company, or software consultancy is unlikely to cause much harm and likely to see major benefit by advertising.
The FIRE sectore, fossil fuels and petrochemicals, fizzy drinks, tobacco, alcohol, junk foods, pharmaceuticals, payday lenders and crisis-oriented financial services (granted a subset of FIRE), infomercials, and major-industry influence marketing (effectively political lobbying through advertising), all carry huge externalities and gain tremendous leverage through advertising which a steep taxation rate should ameliorate.
