Yes, people use it for converting one state currency to another. I did this once to move money out of China.
But these uses are only possible where both states whose currency is being used tolerate it, or lack the enforcement power to prevent it. I only did it once because the site I used had its ability to sell RMB for BTC shut down by the Chinese government, and I never found a replacement.
