Well I think it's kinda a half-baked thing for him to say. We would really need to improve our methods of space travel... We easily could, if NASA could get the funding. Although I'm guessing that's included in the plans, so I think it's a great idea.
If they can get enough funding to put top of the line systems on the ships, that would likely cut down possible loss quite a bit. Heck, maybe they could even create a ship that could not only be reusable, but actually could go to the Moon's orbit as well.
Obviously we do need this, because we're also exhausting the Earth's resources, and space holds much more precious resources we could use. Such as stronger metals, which we could get from capturing asteroids.
This would create tons of jobs for people of all levels if it got off the ground well enough.
This could even be more effective for Earth use as well, if we could get satellites that are tons more advanced than Hubble, they could help military and police efforts.
This is something that definitely has to be done, otherwise the only point to have a NASA is to be an outdated deathtrap.
