Turning to e-money instead of using cash is a nice step. Cash is easy to lose and spoil, it requires significant production costs to make sure that it's hard to fake and it's not very eco-friendly to waste materials on it. Demonetization is a positive trend al long as it does not discriminate those who still use cash and as long as it allows groups who depend on cash to slowly transfer to e-payments. I am not sure that it means going 'faceless', though. When you pay in cash, nobody identifies you. With bank accounts the authorities can trace a lot of personal information and if we are talking about cryptos, at least transactions and wallets can be determined.
