I think it comes down to whether citizens are coerced to part with their personal information or not. If I need access to state programs of food, clothing, shelter, I should be willing to abide by regulations that make it easier to deliver these benefits.

Aadhaar as of now is a direct coercion to part with biometrics and has inadequate features to protect against identity theft. Not having aadhaar means not getting driving license, passport, marriage license etc.
