There are several countries which use a single ID for all government interfacing. For that matter, Aadhaar is almost there already. I am not suggesting that private companies should use it, or should be allowed to use it. But a single ID will limit babudom arbitrariness a bit.

Many IDs (outside India) have similar issues, options to change attributes, and various redressal mechanisms.

It does not in practice, because Aadhaar data is a unverified source of big messes. As several examples:

- UP Gov does not believe Aadhaar to be a proof of date of birth https://www.newsonair.gov.in/up-government-clarifies-that-aa...

- UIDAI has stated that it is not a proof of citizenship, DoB, or address: https://timesofindia.indiatimes.com/city/lucknow/aadhaar-not...

- EPFO no longer accepts it https://www.thehindu.com/news/national/government-makes-citi...

I don't know of how digital IDs are used etc. in other countries and how ubiquitous there usage is. (One ID I'm aware of is social security numbers (SSN) is U.S, but that is considered as PII data and usually companies take steps to protect/mask them). But citing that this is how it is done elsewhere is just an appeal to tradition/common practice and not necessarily addresses the points I had made.
