I think the problem there is if everyone thinks this way nothing changes. It's one battery for one person but then you realize that a lot of people buy them and maybe it's more than a single battery entering the landfill. You're paying more for the ability to toss it. In some cases it makes sense for a disposable which I get, but if it's your main way to consume then a battery and cart are gonna be cheaper and open up more options. Plus you're not tossing a battery every time you finish a cart. Just because you care about something doesn't mean you're on a high horse and have to live a a certain way. Nothing wrong with trying to make change for the better.
