Similarly to air or water, I see no problems with companies building the ships that ply the medium. Do you find it odd that Boeing and Airbus make most of the airplanes that you fly on? Government sets regulation where it can and allows the market to operate within those regulations. You can bet that when and if a lunar, astroid, or any other colony burgeons beyond a sizable hotel that a local government will form and begin to assert its own regulations, not unlike towns of the American west or trading posts operating underneath a larger national trading company. Under what form that occurs has yet to be seen.
