Setting up a Bitcoin node in a remote village doesn't "bring banking capability to the entire village". The node doesn't offer a badly-needed credit facility or the ability to turn remittances into local banknotes (at least not without an actual bank account...), the stuff that can be bought with Bitcoins can't be shipped to the village anyway, a foreign language software program that doesn't run on dumbphones certainly isn't an improvement on their existing cash, mobile and IOU payment systems and is an unimaginably awful way for a technically and financially unsophisticated population to store their life savings. It does offer hope to wealthy Westerners who bought Bitcoin in December that they might recover their losses by dumping on the global poor, I guess.
