If the physical button was free, I wouldn't mind having a few of these to just press when I need some more of something like that. Remembering to write it on a list and bring it with you to the store and pick it up is a bit of a hassle.
This could be pretty handy to have.
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.
"Maybe I can go without wiping my ass this time?"
I think it's more for refilling things you commonly use without needing to worry about them. I can't tell you how many times I've forgotten things like detergent when we were low or out but pressing a button when I notice it's out right after I use it? That's really low friction. It's not a half bad idea in my opinion.
Except your kids won't spam that on your phone, like they would with a physical button.
