How can you not privilege the pattern-instance that right now is posting on LW, if you have no idea if it's the only instance or one of a million, the others being clones I just created in my basement?

Okay, I'll grant you that I privilege the one I am at the moment, but the nine hundred ninety nine thousand nine hundred and ninety nine duplicates will each privilege themselves - and if I knew that they would be created in advance, I would be concerned for what they would experience for the same reason I care about any other future experience of mine.
