Some of us are here to get away from the control that comes with fiat. I would go so far as to assume that some of the more hardcore Bitcoin proponents feel this way. If someone managed to control Bitcoin (which I see as unlikely at this point), many of those hardcore proponents would be gone the next day.
This. Bitcoin controlled by US money supply, directly linked to the Dollar? We already have that, it's called name your bank / Dwolla / PayPal / asdf.
That is not Bitcoin. It functions only through banks, needs no p2p network whatsoever, where's the point?
