Thanks for taking the time to explain to me in such detail. I'm finding this perplexing because to me it's the exact opposite. I was raised non-theist and find 'souls'/non material components completely impossible to believe in. And if l am only those then it isn't me if it gets destroyed.

Consciousness isn't the self. The self is a complex organism that is very much alive and functioning even when it is asleep. If you are in fact a doppelganger you have no way of knowing and neither does the Anomander who died. And that is why I wouldn't risk teleportation.

The arguments of @Zetaphor eksewhere in here describe it better than I can.

This question all comes down to your opinion of what makes a person a person, whether that means we have something greater than the collection of our atoms, or whether we are simply the emergent outcome of the complex arrangement of atoms. If you subscribe to the former then you also need to believe that this machine is somehow capable of either transporting/transplanting that “soul” for lack of a better expression. Where if you subscribe to the latter than this is most certainly a suicide cloning machine.
