Imagine this: - you want to provide LN/ecash services to your family and friends -you don't want to know who is doing what payments, to offer them better privacy - You end up running an ecash mint - you don't want any rando to be able to use/abuse your mint - you need auth (preferably blinded) Also know this: - It's an optional spec - No one is forced to add auth to their mint - you are not forced to use a mint that implements auth Auth has a lot of drawbacks for ecash mints, but in some cases it is an absolute requirement

imagine signal but for your bank account
