You saw what that tiny 20-meter asteroid did to that town on Russia last year right? this one http://en.wikipedia.org/wiki/Chelyabinsk_meteor http://en.wikipedi

  In that case it would be more rational to spend money on asteroid detection and deflection. That would be orders of magnitude cheaper and easier than building a completely self sufficient space colony.

    That's equivalent of patching a legacy code base and delaying the problem not exactly fixing the root cause.

      Your self-sufficient space colony can still be destroyed by asteroids too, so that doesn't solve the problem either. Deflecting asteroids is entirely possible so it isn't a "patch" either. And building a self-sufficient colony would be so ridiculously complicated and expensive, it might not even be possible at all. That sounds more like a "patch".
