In my opinion do not need an ATM, the cost to buy a machine and ATM care is very expensive, who will pay it? Even if it exists only in some special places, it is unlikely that bitcoin ATMs exist in every village, so bitcoin ATMs should not be a top priority
In whole thread i found your point is valid . Who will take care about ATM machine expenses ??. Here is my suggestion there is lots of exchange wallet in each country they can maintain machine if they are having proper plan and then they can charge small amount for transaction.
