This is something I'd strongly disagree with. Perhaps it would be okay if Bitcoins was accepted as some sort of side-service by a financial institution like a bank and that "bank" respects the autonomy of its clients, but having one I guess that kind of forces people to aggregate especially if it's some kind of national one and go through it in order to use bitcoins would defeat the purpose of a decentralized system. It'll be collecting information and having walls for you to need go through before having access which both kind of is why we have bitcoins in the first place.
