The Short Answer

Because having every human being in existence living on one easily destroyed rock is incredibly short sighted. We need to start moving off of earth if we want to survive and evolve as a species. Plus it would be indescribably awesome to know that a member of my species is standing on another planet more than 33 million miles away.
