This is super tangential, but regulation around space access is (ideally) there to prevent congestion, collision, and space debris. It's not hard to imagine a world where space access is abused and bad things end up downwind (Kessler syndrome[0] is a classic example).

To your original point, I'd say that yes, a lot of laws exist because they solved some problem at the time they were introduced (or because someone acted corruptly, but let's ignore that for now). I believe in questioning laws, but when the argument is "it'd make our private endeavors more effective," then I'd carefully consider why the laws were there in the first place.
