The cherry on top is that this whole ritual is to save someone the hassle of "having to deal with batteries". The horror!
I'm not doubting that it's a more rewarding experience, but it always cracks me up when proponents of an obviously more laborious process in anything also feel the need to act like it's easier too.
It's like baking your own bread, making your own pickles, building your own wooden furniture, or making any number of dishes "from scratch". Sure it's probably better in the end, but that's after buying a bunch of stuff, going through a significantly longer and more tricky process, and often after making mistakes and building an entire new skill set.
For most people, all it will become is a lesson in why they preferred the original path of convenience in the first place.
