> My claim is simply that if the aliens have any sense at all they will choose the first option. Does Homo economicus really exist? And even if it did, the ends optimized for are chosen subjectively, aren't they? If the aliens' goal is to possess the original fsvo original, that's their business. Just as it is the vendor's business to set the price of the original at $Y at a price of $X. AFAICT you introduce "... as a bundle of atoms ..." here. Are you proposing that rather that to "actually ship" original or copy, rather than packaging up the original carefully to keep it intact on its journey, you ship a dust that the buyer can reassemble, IKEA-style ("Interstellar Kamprad")? (Even still, they may decide that destroying the original in this way is worth the price premium you're demanding above destroying the atomically-identical copy; who's to say?) Finally, there is some circularity in you asking $X rather than $Y, Y >> X in this case -- if you don't see the difference yourself, why would you have priced them so differently, instead of charging either $X for both or $Y for both, and then randomly choosing to send the copy or the original at that price? For instance, "Because that is the price they are willing to pay? Because that is the price the market will bear?" involve some assumptions about your a priori market knowledge.
