The problem is that arbitrage with fiat is a near impossibility. The forex would be the same thing without brokerage accounts and people arbitraging the different currencies. The exchanges would level out pretty damn quickly if say I or you could buy 10k worth of bitcoins at one exchange, send them to another sell them take the profit and repeat 2-3 times a day and the difference would be almost gone.
