Nice story, but I feel very uncomfortable about the Stradivarius part. That (and to a lesser extent, the way Ted is treated) makes me feel more that it is an utopia for Ishtar, not for humanity as a whole. I don't see how, funtheorically speaking, the potential lost of one of the last Stradivarii and of the hope of duplicating them, allowing for increased musical enjoyment for all humans and all to-be-born humans, can be lower than the slightly higher thrill for a one-day aventure of Ishtar.

Something like "if you chose to sacrifice the Stradivarius, you won't ever be able to hear it, but the rest of humanity still will" would feel much more appropriate to me. But I really don't see an utopia in which, for a bit more of fun of a single person, the whole humanity will lose something like one of the last Stardivarii.
