The situation is complicated elsewhere because we live in a media environment and have a general discourse where bans on ads in which cars make trees grow and flowers bloom would be considered government intrusion on freedom of speech.
So there is a point - still, as regulation is better it should remain the ultimate goal.
If we just wave the "this-should-be-regulated" flag while sniffing at attempts to score points within the media environment (judgement of their quality and likely effectiveness set aside for the sake of argument), I suggest we are comfortably ignoring the way the world works. The image-makers, meanwhile, go on creating their "reality".
