Novelty and luxury are a huge part of our global economy, and as time progresses, I expect that to increase. Yes, it would be an enormous cost to have an original work of art created by an alien master artist shipped to your home / corporate headquarters, but it's the kind of thing that I think those wealthy enough will want, even in a world of 3d printing.
In fact, high cost is a benefit in large parts of the luxury market, as part of the point is often to signal status, so presumably a lot of people will want it exactly to signal that they can afford to have an original instead of those pesky "fake" 3d prints.
