I totally get the convenience angle, being an Apple ecosystem dweller myself. However, with more and more of identities, payments moving to a single device the recovery workflow should be hassle free.
With physical documents, my IDs are spread out so if I lose my drivers' license I can pull out my passport to get a new one. How will it look like in Apple world? I haven't read the recovery workflow documented anywhere.
Imagine being on a business trip say ~5 years down the line and losing your phone. Your hotel key is gone, passport is gone, no money, no one to call, no app, no internet. Now what?
