I read that article a year ago I believe. If hyper local private banks (think family or town owned) is your answer then I would say that all that does is shift the responsibility from the individual to another individual or group and centralizes a bunch of wallets into one main database of keys that makes it an even juicier target for hackers and more likely to get compromised if the person or group managing the hyper local bank is less not up to snuff on their IT security knowledge.
