It also makes sure you don't question your consumption habits, shop around for better deals or look at the competition.
Seriously though, do I question my habits when buying food, drinks and coffee. This video is saying "you can lock yourself into a cycle of dependence on this one brand of coffee and this one brand of water and this one brand of cheap unhealthy ready-made packaged food".
Either you find that unpalatable in principle or you don't. It's probably a cultural thing.
Personally, I buy the same stuff over and over because it doesn't matter. I don't want to spend time worrying about things that don't matter.
