I too support all initiatives you list but not at the risk of handing away by identity for potential abuse. You have to understand that most Aadhaar critics are not anti-national or corrupt, in fact quite the opposite they do not want to become (even more) vulnerable to the 'big players ' in the hierarchy of corruption in India.
I will also welcome all methods which
- eliminate the middleman
- reduce the sense of entitlement from government officials
- abolish the need of standing in queues of people to pay bribe
- financially drain out all those government officials who plan their expenses based on bribe estimate not their actual salary
Aadhar's direct benefit scheme has actually done it.
