"Companies vying to turn asteroids into filling stations"<p>No they aren't. This is complete nonsense. Companies are not vying for this at all. The title is total rubbish.
If you can independently get to the moon or an asteroid, I feel you can do what you want. Legal declarations from parent countries and kindoms always try to curtail or control what colonists in new lands do. While somewhat effective in the early years of settlements when external support is still needed, eventually the settlers have ideas of their own.
