The article doesn't make an argument around biometrics. Biometrics are needed even for getting a passport or registering a property purchase, but notice how those are never brought up in any argument around Aadhaar's use of biometrics, whether arguing for or against.
Procedural speed-ups are not because of the technology of Aadhaar, but because of the regulatory regime favouring it. The same fast processes also work without Aadhaar wherever there's been regulatory pushback against mandatory Aadhaar. For instance, video KYC works just fine without Aadhaar, and CKYC with just PAN also does instant KYC.
These are procedural decisions, not technological improvement with Aadhaar. Dig into how it works and you'll find that the technology isn't even where they claim it is.
