I wonder if advertisement was illegal, would that have effects on the economy other than the advertisement platforms not getting their cut?

I mean, in Europe there are no drug or doctor advertisements and in US there is. In London or Brussels the outdoor advertisements are much more limited than what’s happening in Tokyo or Istanbul. Do Europeans miss out on medicine? Do London business do worse than Istanbul?

I suspect that there’s a case for getting rid of advertisements but on the other hand the advertisement agencies are responsible for some of the greatest advancements in AI and computing, so maybe that’s the utility after all.
