I would say that a ban on all advertising is not possible to implement in reality.

Its probably not the best option either, given some utility of advertising, such as general awareness of products and services, as other posters have stated.

I'd be eager to see much more limitation/regulation on advertising. In many countries (other than the US) there is tremendous regulation around medical devices, services and products - I would welcome the same sorts of regulation being applied to all products and services.
