This implies that un has jurisdiction over all orbits, which it can't really enforce. Also, good luck getting any kind of int'l tax passed; no one wants to give up that kind of sovereignty. Were I a company, I'd just wait until office changed and whatever treaty this was got torn up to put up my satellites. How could the un enforce this? At the end of the day, policies are enforced with the threat of force in response to non-compliance; fact is, un has precious little of that. The only viable enforcement mechanism would be enforcement by other nations; again, sovereignty issue. Also, what if a nation decides she does not agree to such an agreement?
