The BJP govt. has cannily crafted a message where anyone who opposes this move is branded a traitor and conversely anyone who supports it must be a patriot - this is largely responsible for the "positive" feelings many people have around this move. That and the fact that the internet savvy already used Credit cards so they were largely shielded from this. The Demonetization on the whole was a failure:

1) The strongest reason for pushing it was as an attack on "Black Money" (undeclared wealth outside the taxation net). More than 90 -95% of the demonetized currency is back in the coffers. This magical "back money" is nowhere to be found.

2) The growth rate fell by at least 1% - whatever the other impact this by itself means a massive loss.

3) A large number of "cash only" small-scale businesses have been badly hit - these people are not internet savvy and do not have a voice but they do exist

4) The so called "leap" to a digital economy is mostly a temporary phenomena - just wait till the new currency is available in sufficient quantities

So on balance - all the pain and suffering of the people will NOT bear the reward most of them think it would.
