Good point, but I am not sure if you can compare IP laws with money transmission laws just like that.

For example, in the case you mentioned, DreamWorks is a company and they were trying to protect their IP by suing Pirate Bay. But in the case of money, it's not a company that will go after you, but the executive branch of the US government. I think that's a big difference.

However, I am pretty sure anyway the US does not care where you server is when it comes to money. If you're serving US customers, you're subject to US law. Else you need to geofence the US.
