I agree with a lot of what Dr. West said, but there's a real problem: If wishes were horses, peasants would ride. That's an old saying my wife always uses.
If you go back to the origins of the outer space treaty, it was a bilateral deal that ended up in the UN, and everyone happily signed on when only the United States and the Soviet Union were actors in space. It was a deal over issues about transiting over, for intelligence reasons, both countries. The lesson of all that and the lesson of these arms control agreements—such as the 2002 notification agreement between the United States and Russia, which is basically defunct now—is that unless you have the great powers on board, you're going nowhere.
China, Russia—I'm not sure about India—and even the United States are really not interested in codifying. For the Americans, the fundamental reason is that, through their experience during the heyday of arms control in the 1970s and 1980s, they kept finding the Russians were cheating all the time. They have no reliance, and the United States, despite what many people think, is a country guided by the rule of law. The fear of the Americans is that if we have deep international regulations, we will be handicapped and handcuffed, but our adversaries will not be handcuffed.
If I could quickly add one thing, don't misunderstand that there are probably a series of tacit agreements between the major space players on go and no-go behaviours and zones.
