Is this like the US and the SSN, which was originally only meant for social security, but is now used for anything and everything and many systems require it if you want to do business at all, even though the business isn't related to social security at all?

It's slightly similar, but a lot more dangerous since it has biometrics attached to it (ten fingerprints and two iris scans). There are no data privacy laws in India, and if someone faces misuse or loss or harm caused by this, they cannot even sue the other party because the legal act (Aadhaar Act) gives the right to sue only to the issuing authority (UIDAI). And UIDAI has a very poor track record of punishing the criminals and instead goes after those who point to flaws in the system.
