So you'd consider yourself someone else, despite being identical in ever single aspect save position, having all your personality traits and memories?
I officially name your school of though the "Ten-Thousand Kirk" school of philosophy.
Well if I was dead, in the "taken apart and re-constituted in another location" kind of transporter, then my pov doesn't matter for anyone but me. To everyone else, I would be the same person and they'd be able to interact with the transport-clone as much as they would with me. In that sense, if I knew what the transporter was, I wouldn't go into it.
But if I wasn't dead, in the "We scan your body and make a new one in the new location, and your body doesn't need to be destroyed" sense, then I would be the original and the new copy would be an identical-but-seperate person. I wouldn't suddenly start seeing things through their eyes or having twice the brain-power.
In either case, from my point of view, I am still ME and the copy is someone else, either because I still exist or because I am dead.
From the copys point of view, it would be happy to be alive and would probably not care that it was a copy. How it would see itself and whether it would consider the me-before-transport to be to it's own perspective, I don't know. I would have to get into that situation to be sure.
All I'm mainly saying is that, the me-before-copying would not instigate the copy/transport/upload, because I would view it as a form of death of my "I", and would rather just walk or do a slow-transition. After-the-fact, I would not care, because I'd either be alive and have a clone, I'd be dead, or I'd be a copy. But I, as in right now, would not want to do it.
What about quantum teleportation? You are entangled with a Descan-shaped and sized analogue (forget about the technical limitations of this), and then, at a later point the Universe yells "SWITCH PLACES!" and you do.
AFAIK quantum teleportation isn't a thing, and entanglement is more information-transfer. So it wouldn't be so much as "SWITCH PLACES" as it is "JIGGLE IN THE SAME FORMATION DESPITE THAT BEING VERY VERY UNLIKELY!"
Plus I'm pretty sure it's physically impossible for a particle that's part of a larger system (I.E. one of my atoms) to be entangled. You need to seperate and isolate them a LOT, like "in a near-perfect vacuum without any energy emissions touching it" isolated.
