Why would I want you to manage it? Are you making a phone I want to buy?

Just because I'm happy with some corporations having a scan of my driver's license doesn't mean I'm happy with anybody having it.

Are you already storing the details of millions of others, and mine is nothing special? Are you a publicly traded corporation accountable to shareholders? Are you a nation-state with procedures around all these things? Or are you a criminal trying to sign up for credit cards in my name?

Your supposed equivalence isn't an equivalence at all.
