This is one of the longest and most interesting threads I've read in a long while.
And since Paypal bought a bank to become legit, what stops some entity from becoming a bank somewhere, and allowing whatever crypto currency (heck, all of the respectable ones) and lets you get a Visa/Mastercard that lets you buy stuff anywhere, meaning they, in real-time, auto-denominate your crypto coins in whatever jurisdictional currency you are active in, and if you have enough to buy the thing in question, it's yours!
And for liquidity, the bank in question could simply API into coin base/cryptsy or whatever else is trading stuff, and sell off your coins when you transact (and what do they need to cover? Just the value fluctuation, not linked to any fiat currency, since they run to zero value as time goes to infinity).
Probably the Visa/Mastercard dudes will require a settlement in some fiat currency, so the coins would be settled to that, whatever it is.
