Is corruption inevitable in space colonization?
Yes, corruption is almost guaranteed when any colony is distanced from the mother land. That has been true with all colonies here on Earth & I see no way to avoid that when other planets are eventually colonized. The inhabitants will eventually have to deal with the corruption themselves as most colonies here on Earth have done. Differing conditions require different solutions. However most new colonies require an authoritarian rule if they are to survive the early days of colonization. Like all colonization projects the 1st off Earth colony will be an economic venture by either a country or corporation.
