@David Anderson,

Actually, it is not just "untested theory." Nations and organizations of nations have been making and enforcing laws with extra-territorial implications for a very long time. The USA does it a great deal.

The idea that such laws just "abolish the existence of other sovereign nations states" is a bit silly. It's perfectly possible to have a physical space to which laws apply from several different jurisdictions. An aircraft is a good example. No-one claims that the USA/EU/NAFTA etc is "abolish[ing] the existence of other sovereign nations states" because they (among others) regulate the operation of an aircraft.
