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.
Maybe you're right about those particular things (but maybe in a dystopian future you would because the interference with competition drove the price up into local maxima).
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.
Why all of this talk about a dystopian future? I can choose to refill on a particular brand of paper towels without giving up my right to choose what I eat. This entire thread is full of absurdity.
The conversation started about consumables like laundry detergent and paper towels, not food and drinks. So I'm not sure why food and drinks came up, and then why the further jump to "unhealthy" food and drinks.
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.
No point dragging this out. But this conversation started with a video about how you can order things including food (e.g. microwave ready made food) and drinks (coffee and bottled water).
