Seems great for all the basic research it will require. But I'm unsure about the morality of it. I think the drive to expand and discover new things is perhaps a direct cause of the deeper problems we have on Earth. Would humanity be better off just becoming a sustainable population of monks? Or are we morally equivalent to a virus, reduced to survival of the fittest and always seeking out the next host to reap?
But even if we go farm out every other planet and make it barren and even if we mined every ounce of every other planet in our galaxy... if we're the only life in the area, or the only life in the universe, it doesn't matter one bit. We could blow up every single other planet and it wouldn't hurt us at all, because we can't live there.
So the only thing that makes sense is to keep living like we are the only life in the universe, all the while trying to figure out if that's true or not. Mars isn't alive. Venus isn't alive. The moon isn't alive. It's not "reaping" a "host" any more than me painting the walls of my house is. It doesn't make one lick of difference. There's nothing immoral about spreading to other lifeless planets.
