That's a valid point. The scientists are focusing their abilities to solve the logistics of it but, solving this issue might help with solving another. Teams of individuals will need to come together to solve the issue of how to populate an area in a place that is (without human intervention) uninhabitable. The idea that I was hoping to put forward was that this effort would be more rewarding to society and humans as a species if it were directed towards solving the fundamental problem of homelessness in general.
