It's not only about poor impulse control. A lot of those techniques work in such a way that people don't even realise that something is trying to influence their behaviour. Usually, these techniques "catch" people when they are off guard. There is a lot of psychological literature describing how unreasonable people behave for the most of the time.
Sadly, when it comes to manipulation, human kind has already lost this battle.
I think you overestimate the power of these techniques. They don't add up to making people buy things they don't want. They just change the perception of the goods' value or cost. No matter how many ads I get shown, I'm not going to buy a McDonalds unless I'm hungry and want something quick and cheap that I don't have to cook. They just use adverts to position themselves as a good choice in that situation, or to improve the public impression of the meat they use (and such claims are legally required to be true so they can't just say "we use great beef" and cook you up a rat burger).
