Well, Lothar, if we establish self sustaining colonies on the moon, Mars and the moons of the outer planets, we will help ensure the survival of mankind, should a comet or asteroid hit and devastate the Earth.
Also, we can mine Helium 3 from the Moon.
This element can power the Earth for a thousand years, and do it far more efficiently than anything we have now can do.
