Sure sure, and I lose the ability to keep a phone going 6+ years because the battery is glued into the case. So I'm making 3x the e-waste for... really nothing honestly.
In terms of power banks, I'm currently hoarding my friend's disposable vapes which all have fairly high output LiPO batteries in them. All I need once I'm done harvesting is a few 3D printed parts, a aliexpress BMS, and some wiring, and I'll have way more capacity than I know what to do with for very, very cheap. BMS is the most expensive part really, the rest is a few bucks, and, if I kill a cell, well, there's an abundance of disposable vape batteries available.
