Somewhat off-topic now, but your comparison with Libya is about spot-on. I lived and worked there in 2010-2011, and it was much the same - an isolated, sanction-riddled, failing state, where it was nigh on impossible to change money. Luckily, I worked for an organisation which could send money overseas to a home-country bank account, so it wasn't an issue. Here in Burma, it is becoming increasingly difficult to buy dollars, which is why my company now pays 25% in local currency. The official exchange rate for dollars has risen as high as x5 on the black market, prices are astronomical (as Myanmar manufactures relatively little, and must import things), and all the rest of it. End result - if you want to travel outside the country, you need to take dollars, and hope to find someone to change them at a decent rate.
