People colonise not just to get more room or resources. North America was colonised by people who wanted to get away from the political situation at home. Australia was colonised because the government wanted to get criminal away from Britain. (And other strategic reasons, yes yes, whatever.) In both cases, colonisation was desirable in order for some people to be able to put some distance between them and some other people. And this desire won&#x27;t go away.<p>Imagine, the solar system would be a more harmonious place if everyone with rather strong ideas about how the world should be run could simply go start their own world to be run that way. You could have a libertarian planet, a socialist planet, a centre-left planet, a centre-right planet, and if someone didn&#x27;t like the way things were run they could move to a new planet. Of course there&#x27;s not enough planets for that, but there&#x27;s enough raw materials to build enough orbital habitats.
