The connections to Aadhar is far more interesting than is mentioned in the article. There is a revolving door between USAID's 'Catalyst' promoting cashless transactions, Aadhar and the people who benefited from demonetization. The Indian state has also been extremely antagonistic to Bitcoin and other such 'anarchist' platforms.

The state apparatus often grumbles about 'terrorism' and how internet has made things difficult for them. Infact, the minister incharge of IT was quoted as saying in 2011 that internet access needs to be moderated with IDs (guess which one). It's almost certain that such legislation will be authorized in the coming decade - perhaps sooner if the "i-patriot" act which is in the waiting (in the US) passes earlier.
It may very well be that the retainers of the East India company (aka deep state) are planning on selling the nation for a few pieces of silver again - which would explain why policies remain uniformly the same with every dispensation. Would not be the first time, and should not be surprising. However, since history education follows the colonial model of cryptic self-justification, it should not surprise anyone that clear foreign geopolitical moves (India has close to half a trillion of IMF/WB loans) are now seen as 'nationalistic'.
It'll be very interesting to see how this proceeds in India - given its hostile stance on Bitcoin. I'm betting the state will welcome it with open arms and will probably proceed to tie it to UPI. In fact this could take a big share of the foreign remittance market, and could rope in Indian banks in to influence the state. I imagine people like Nandan Nilekani, who illegally pushed the 'Big Brother' project, will play crucial roles here.
