I agree that there are undeniable benefits from Aadhar. However, the issue is that the narrative from the govt has been that it's an either or situation. Either you have the convenience of Aadhaar, or you have privacy. This is unequivocally false. The solution isn't even technical. There are two simple, easily doable fixes which will deliver most of the benefits without significantly eroding privacy.

1. Ensure that legally valid ids other than Aadhaar are not treated as second class by any govt department. If a non Aadhaar id is refused, the reason must be given in writing. The problem is govt babus like the ease of Aadhaar and hence refuse to do the tiny bit of extra work needed on the non Aadhaar path.

2. Amend the Aadhaar act to ban the use of Aadhaar for anything except identity verification. If any personal data linked to Aadhaar is saved by a platform, then they are liable for leak of the data in the event of a breach.

Just doing these will enable the use of Aadhaar for it's original intent which was verifiable identity. The privacy degradation comes from using Aadhaar as a primary key for arbitrary storage of personal data, not from the existence of Aadhaar itself.
