Provided that you're not throwing the excess out, it's not too bad? They're reusable but they do wear out eventually, and when that happens you can just draw from the backlog.
Alternatively you can always use them for other things - I don't keep 37 of them, but the handful I have I'm always using for stuff which isn't just groceries.
Genuinely so disturbing that people are cheering this on, both in general and in the context of these folks being just regular people.
