His article considered moving money between the US and France as a fiat->bitcoin->fiat transaction. This is a version of the "international remittance" problem we promote as one of the killer apps for bitcoin.
Two notes:
1. He tried to do this all manually, and therefore had to spend some effort to 'set everything up' and he also had to accept some currency exchange risk. For bitcoin to succeed in this application, we need to wait for the 'BitPay of Remittance' to enter the scene (or build it!). At this point, the remittance service will absorb the volatility risk while still performing the transaction cheaper, faster, and easier than the legacy system.
2. In a more distant Bitcoin Economy, international remittance is just a bitcoin->bitcoin transfer.
Or use an ATM and deposit fiat directly to the recipient's wallet. Done.
