I don’t think Harry is actually taking the piss, and nor does he see it as a literal proof. It helps to remember who he’s talking to. He’s trying to get Dumbledore to consider not just death, sometime in the far abstract future, but a thing that you might actually welcome even just one day after a day when you didn’t welcome it. Not a proof but a rhetorical device.
Well, and here’s where it gets interesting: are there any other places where we see Harry use logic that he knows (or should know) to be unsound in an instrumental fashion? That is, where he makes a tactical choice to argue nonsense, believing it to have a better chance of convincing someone who disagrees with him?
Harry should consider the possibility that he “might actually welcome [death] even just one day after a day when [he] didn’t welcome it”—if he can’t anticipate the possibility of his utility function changing based on an infinity of new evidence, he should stop pretending to be solely rationalist. Which, interestingly, Chapter 82 seems to be hinting at.
