I haven't fleshed out the thought, but I've always thought it would be ideal if you were able to keep control of your data at all times.

You have a record of your details secured with locally stored biometrics and systems can reference that data with your consent (and an audit history) That way you don't need hundreds of accounts just to order food, products etc.

So the third-party never knows who you are, or where you're located, but are able to use your location by referencing your location record. That way they don't need to store any data about you.
