To my growing fan club:
The difference is perspective. You can't change the perspective from which you view the world no matter how many copies of yourself you make. You'll still be you, looking out of your eyes, feeling with your hands, living in your body.
You will still feel those last moments of fear as your body fails you and you will still descend into whatever eternal nothingness there is that awaits us all. Why would you feel good about some other you living on?
That is a totally valid point, and question. The other me may be other, but it would also be me. I consider my person to be the continuing of an individual perspective. What I am talking about is the duplication of that perspective. A me would still die, but as far as the other me would be concerned it would have went to sleep for a procedure and woken up immortal. Original me would die happy knowing that my person (the only part of me that really matters) isn't gone forever. And just to be safe I would will all of my stuff to my other me, just in case the courts end up thinking the way you seem to.
Of course that's not as clean of a solution as some magic formula that grants biological immortality, but it seems a hell of a lot more plausible to me. Plus this kind of immortality allows literal respawns in case I decide to visit historic Somalia and end up painting the sand with android brains.

This particle is not a person.
This neuron is not a person.
etc etc
ergo this body is not a person.
ergo the person must be separate from the body.
That is the basic form of an argument you keep making, yet if you contrast it with this counterexample it's obviously a bullshit argument.
A tire is not too heavy for me to lift.
A windshield is not too heavy for me to lift.
etc etc
ergo, a car is not too heavy for me to lift.
The car's weight and the body's person are both
emergent properties.

If you can't fathom why (to continue your tired example) torture is bad unless we all have souls, I don't know if I can really help you. But perhaps this is in terms you can understand: do non-human animals have souls, and is it acceptable to torture animals?
Assuming you think such animals do have souls: what is it then that separates humans from other animals?
"Not (yet) having observed something does not mean it doesn't exist."
That is totally accurate, but misleading on its own.
There, is the horse dead yet?
