At the end of the day, India's model of development is based on much more statist Japan, South Korea, and Singapore's, as most advising, developmental grants, and FDI in India is furnished by these 3 countries.
While India may speak English, it's administrative system and legal system is closer to Malaysia and Singapore's in jurisprudence and central control, and as such, administrative leadership in India tends to look at Singapore as a model - heck, Narendra Modi was mentored by Lee Kuan Yew when he was CM of Gujarat.
Aadhaar itself was developed in coordination with Singapore, and is directly based on Malaysia's MyKad and Singapore's NRIC.
Aadhaar has had disastrous pitfalls with rollout, but it is complete at this point - especially with COVID acting as a forcing function.
