I think your overstating the effect advertising has over people. Sure seeing an ad may end with me buying something I would't normally have bought, but it in no way forced me to do so.
If a commercial comes on for some new resturant and it looks good to me I may go there. If it turns out I enjoyed eating there then the commercial has actually benifited me by introducing me to a something I may not have otherwise come across.
All ads can do is put information infront of people and they make their own decisions from that, in no way is it "controlling people's actions and making them do harmful things against their will". If you have some proof that advertising is capable of some how controlling a persons mind I would be very interested to see it, but short of untruthful ads there is no real harm to them. At least not beyond whatever loss of enjoyment seeing them may cause.
