If one were to launch satellites over the United States that communicate with transponders set up in Mexico, the Caribbean, Greenland, and Canada, would that be outside scope of the FCC's jurisdiction?
In general those countries have their own rules that while different amount to the same with different details. The smaller countries generally copy what the US does (or possibly what the EU does).
While you might be able to find a country to let you pick your own rules, you will only be able to talk to your satellite which means you can't do much with it. Most satellite are used for communicating to people on the ground and if you can't communicate to the US the satellite is much less valuable.
