I wonder about that idea. I mean, thinking about it there's almost nothing found outside of earth that's worth the cost of the infrastructure needed to bring it inside of Earth's gravity well. Which is a bummer. The only thoughts I have contra that are that it's only expensive if you count the cost of the infrastructure - given that moving resources from outside of Earth to it isn't super unattractive. Second it's possible that costs should be viewed not just Earth to outside of Earth but also outside of Earth to outside of Earth. That is to say mining water on the Moon doesn't make sense if the destination is Earth - it the destination on the other hand is another part of the Moon there might be some logic to it. You could in theory be cost competitive with the Earth as you don't have to get it out of Earth's gravity.
