Seems to be just a bit too grandiose and exalting for a policy to declare activities in space are for the benefit of mankind. US policy probably needs to focus on how outside domains have a relationship with our domain. If mankind didn't create space, and if there are elements of God's creation in space but outside our domain which are skew to our domain, then it's foolish to make such universal claims.
It might also be the case that some activity in space be used for the benefit of the individual independent of the whole of mankind where no material damage to mankind exists.
<;^) If a space lion attacks an astronaut, then the astronaut should be allowed to defend himself with his space lion hunting rifle, regardless of any legislation,....(hahahaha)
