Lunar property rights? Now there is a fascinating topic!
I dont' see how any of the internationalist types around could oppose such an amendment to the space treaties with this sort of language.
How do international laws affect private businesses on the open sea? Are they held responsible according to their home country? How about multi-national companies like GE? I find this fitting since it is possible that a well funded private group might have a go at space one of these millenia.
