What little I understand of economics is through anecdotes. Most middle aged women have dealt with maids whose husbands take away their money to drink or worse to buy goodies for his mistress.
The concept of going cashless and giving everything through banks, makes such women very vulnerable. At present, such women usually hide cash in the rice dabba or leave money with the "memsahibs" to be used later when children's fees are due. They are able to save some money from their husbands. If all money goes into the bank, the husband is sure to get hold of it one way or another and drink it off.
The money transfers to be given through various government schemes in lieu of subsidies or food will eventually be drunk in many cases.
