This is quite asinine. I assume you've never tried to purchase an item in country A from merchant A' accepting currency A'', while you are in country B using bank B' with an account denominated in B''. The hurdles, generally, are numerous and diverse. Any lack of hurdles is quite exceptional, and completely dependent upon international agreements between nations, banks, and any number of permutations thereof.
Instead, you could simply transact in BTC.
In my country at least, if you want to purchase something online and in a different currency than your account and CC's denomination, the conversion is done automatically for you at checkout, at whatever the bank has set for the rate, usually a fair one. Works like this regardless of what store you buy from, could be in the U.S, Europe or somewhere else on the globe.

People in less developed countries don't buy online not because they don't have credit cards, they don't buy because they don't have money. If you make $5/day, bitcoin doesn't suddenly give you the ability to buy brand new iPhone.
If you know how to move money quickly between those locations, you can make lots of money. It isn't easy problem, because otherwise the arbitrage opportunity wouldn't exist.
Not sure I'm following.
All of the rampant downvoting on this thread and blinkered discussion regarding Bitcoin really bothers me.. it sounds like /r/bitcoin has taken over HN.
Don't get me wrong, I believe bitcoin is the future of payments. I have absolutely no doubt that in the coming years it will become a global payments infrastructure that will destroy the idea of an international money transfer and change global e-commerce and payments forever. But the idea that it is already there is totally misguided. OP is right. There is no sense at all to use BTC to purchase legal items in the vast majority of countries.
I've had quite a few bad experiences trying to purchase internationally (if your billing address and your shipping address are in different countries, you're in for trouble), but I don't think BTC solves any of those. BTC doesn't solve the shipping part, and BTC doesn't solve the fact that some stuff isn't internationally available (for example, music/movies/TV shows).
I'm speechless.
Get it?
