Well, that's not just a legal barrier there, but also that the people on the other side of that transaction don't like to be robbed.

People deal in currency blackmarkets all the time, and all participants are willing. Obviously, being able to do business out in the open is much more efficient and productive. And especially eg Amazon as an above board organisation could not engage in blackmarket operations without endangering their legal activities.
