The whole point of using a decentralized currency was to *reduce* transaction costs, dammit! Using the 9,000 intermediaries and such BS to transact on the man's grid is of course gonna fail. The only place I see it as useful at all is direct or escrowed exchanges; and I'm pretty sure automated BtC escrow can be done for cheaper for $35 -- but not if you worry about "Know your Customer" and the rest of the snitch grid shit.
