They can exchange in physical currency which would be acceptable in most third world countries and with the amount physical currency floating around they wouldn't need to get any from the US, no?
I don't think you could do that at any scale and escape the wrath of the US.
That runs afoul of most money laundering regulations, so if you have any presence in the US they'll go after you, and they'll prosecute anyone with any serious connection to it and extradite those people to the US where possible.
Moving money across international borders is not a problem you can just engineer around. You have to play by the rules.
If for example you require a third party exchange to sell to fiat currency, that should work.
But that exchange has to do the KYC stuff and the unbanked are still cut out.
Now if it's a local exchange for a local currency, not USD then is fine.
