It’s not like your screwdriver example at all. It’s like saying I already have my nostr private key in my iOS device and I don’t want to paste it anywhere else on any device, Android, desktop, or otherwise. I want the signer app that I have a use on my primary device to be able to sign into any app on any device. You’re obviously intelligent enough to understand this but you play dumb and throw a hissy fit any time someone doesn’t agree with you.
