An interesting notion - it would be an interesting case to see if exporting rocket components to "not a country" would violate ITAR. That hasn't stopped Iran from getting launching satellites into orbit though, and misses that e.g. ULA buys their rocket engines from Russia where ITAR obviously isn't a problem.
It seems like it would be very difficult to export to "not a country." Every dry rock in the world is claimed by some nation, and ships and platforms on the open ocean are flagged and/or operated by citizens of some existing nation. Many U.S. laws apply to U.S. citizens no matter where they are in the world.
