You don't find your subjective self go somewhere else when you get drunk or something of this kind, do you? Why should death be different? Why if you are to be anaesthetised, then suffer some minor brain damage, you don't expect to be saved by vastness of the universe? If you end up in 'closest match', clearly the enormous spatial distance (where all the information within your head is encoded into spatial coordinates) should make those more distant from you. Are you sure they are closest to you when you die, rather than someone alive and well nearby?

I believe that such notions are easily falsifiable and have been already falsified in just about anyone's subjective history. If I had a subjective history of crazy rare coincidences happening to prevent me from ever bumping my head on anything, or indeed prevent me from any other changes in the brain such as maturation, then yes i'd be a believer in this. Alas, none of that was observed, so no.
