I already don't question my habits for paper towels or laundry detergent. I buy the same ones every time because it works and it's not worth optimizing the $20 of paper towels or detergent I'll buy every 6 months.
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.
