When all the impossible things get eliminated and we move on like good rationalists, there are still choices to be made, and some things are still better than others. If I have to choose between a universe containing a bilion paperclips and a universe containing a single frozen dinosaur, my preference for ice cream over dirt is irrelevant, but I can still make a choice, and can still have a preference for the dinosaur (or the paperclips, whatever I happen to think is best).

I agree and think that this part sums up a good response to the above question.
