Could you imagine how bad it would be if Congress got excited about the potential for internet crime in 1985, tried to guess the form of the problems that would arise, and then wrote laws banning and permitting things that they thought would lead to trouble? There is no way somebody back then could predict which situations would lead to trouble decades later.
The best way to deal with space would probably be to let judges stretch earth law (property rights, whatever) to produce as much justice as possible, and then modifying the laws once the lessons had been borne out.
