If you operated such a hut outside the jurisdiction of the US, it doesn't matter what laws the US has, they don't apply to you. I don't know what a 'hut' is in this context, but if it's connected to the USD payment system, not only can the long arm of the U.S. try to apply itself, but the said hut can be cut off via pressure on the international banking system. For the former, see the links I sent, which includes a case about New York State applying laws to an overseas entity; for the former, consider Iran and sanctions. If your hut consists of a person shuffling US currency around with thumbs and rubber bands, well, that's a different story.
