I'm going to ignore the personal jibes you've made and ask you a couple of simple questions. No hand-waving answers please. 1. I'm a shopkeeper in 2017 and all my black money is gone: burnt it, paid a fine on it, whatever. A customer comes in and makes a purchase on a new currency note. What prevents me from not reporting this to the tax authority _because_ of 2016's demonetisation? Note that there is no tracking of cash. 2. I'm a corrupt government official and I want some 'mithai' to select your tender application. I want to get paid in new 2000 rupee notes. What stops me from accepting a cash bribe?
