thinking forward a century or so, space
Space colonizers want to gain the historically dangerous and irresponsible political power to hold planet Earth hostage from the heavens. Space explorers want to freely extend human space capabilities to everyone on Earth regardless of social status with no threat towards homeward. The two are mutually exclusive, and the longer private enterprise is allowed to develop offword technology, the greater potential for betrayal of the common good of Earth and all its species.
Equal exploration opportunity and space access will be as important as ensuring nuclear disarmament in the long run.
