“The nightmare scenario of a space monopoly isn’t too different from the fear of a monopoly here on Earth. If just one company gains too much control over the space market and gets too far ahead with its tech, it’s possible that future competitors could be blocked out of space for good. That means a single company, like SpaceX, could end up with an enormous amount of influence over how humans visit and utilize resources in space.”
