Not an argentinean, but I don't think that's the right way to look at it.

You can exchange dollars in any country and in many you can directly pay in stores if the storekeeper is flexible. You wouldn't call that a parallel dollar economy.

The only additional point in Argentina is thay they have an official exchange rate that is way way different from the true exchange rate (ie the one that arises from demand and supply). That's why you can exchange dollars through the official channels and get, say, 500 pesos, or you can exchange from an unofficial one and get 1000 pesos
