This doesn't seem to say anything about the boundedness of human utility functions (which I think is pretty likely) that Pascal's mugging doesn't.

Pascal's mugging requires the victim to say what probability he assigns to the mugger being honest, and this one doesn't, so with this one I can fleece people en masse without having to have a conversation with each one.

Also, Pascal's Wager as presented on LW involved creating other people, so this version avoids Hanson's suggestion of assuming that you don't control whether you're the preexisting person or one of the new persons. This version works with an unbounded utility function that does not involve creating other people to get large utilities.

Otherwise, I agree.

ETA: Another advantage of the scenario in the OP over Pascal's Mugging as presented on LessWrong is that the latter is extortion and the former is not, and people seem really keen on manipulating the extortioner when there is extortion. The OP managed not to trigger that.
