I do not see any contradiction in pursuing all of them together: stopping corruption", "going cashless", "cash saved at home to cheap loans". And corruption is not something that a single step or policy can fix. It would be rather stupid of government or politicians to put all effort on a single goal.

It seems to me critics show a deep disconnect with people when they claim failure due to inconvenience to people. In India riots can occur on far minor issues than demonetization. So yes people are willing to wait for results but critics are hastily jumping to conclusion that scheme has failed.
