We need more local exchanges in every country, because bank transfer is almost free if you send in the same currency.
Moreover, if all such exchanges implement free transfers between accounts on the exchange than it would be possible to transfer/convert fiat money to any country in the world.
1. Transfer fiat money to your local exchange.
2. Convert to BTC.
3. Transfer to an exchange local to payee.
4. Convert BTC into payee's currency.
5 Transfer money in payee's currency to payee account.
6. Payee withdraws fiat currency to his local bank account.
7. Banks and other middle men do not profit. (some fees to exchanges would apply, though)
Transacting in BTC still seems to be so much easier.
That wouldn't be as easy as you said. You would need to create an account on two different exchanges (one in each country), and you would be exposed to bitcoin value fluctuations between steps 2-4.
BTW, it won't be long before exchanges will start requiring ID.
