I'm strongly sympathetic to the idea that these ads are just not very useful to people, in that they don't positively contribute to their health, and add just that little bit more stress onto the healthcare system. I can't help but think trying to forbid them is the wrong way to go though. Trying to restrict the flow of information feels like it has to be counter-productive and it certainly looks a lot like "ignorance is bliss", and I KNOW that it's just getting harder and more ineffective as time goes by.
