Wasn't there a post by Gaty with the same title?
Ok, well, it's a matter of sustainability....
How to reach it?
By susbstantially reducing the costs of launching a manned spacecraft, not by relying on countries that practise lower costs (which can change) but by really showing it can be done and it looks like t/space is showing a promising way to do it.
But it's LEO, not the Moon nor Mars.
LEO means space station, international patners, various customers, tourism, earth observation, being observed from Earth....Manned spaceflight is a lot more sustainable in Low Earth Orbit.
Now, higher orbits could be reached from LEO, or even turning around the Moon for not much more.
But the Moon will require a political long term commitment and a strong desire from the population to do it. It's different.
