No matter what you do the Earth won't stay habitable forever. So we either learn to expand out into space as a species or face extinction eventually. Not to mention putting all our eggs in one basket is a terrible idea. Any cosmological event could wipe out the Earth at any time. The question is are you okay with our entire species going with it?
