ha, nice try mugger, but if I don't give you my wallet, you won't be stabbing me, you'll just be stabbing a totally different person-moment in the future that remembers being me
ha, nice try tetraspace, but we both know that factoring experience into different "person-moments" is fallacious, an illusion brought on my memory. there's one cosmic person which is everywhere and everywhen with a single eternal experience
ha, nice try mugger, because if that it so, then the cosmic experience would just be stabbing itself, and likewise the cosmic experience would just be giving its wallet to itself, and this would be futile, it would only make sense for it to be in a state that's best for itself
and then we both gave our wallets to effective charities
