Do you believe that IF you vanished at point A and a copy of you created
at point B who was physically and mentally similar to the original to the same
extent as if you had walked from A to B you would have survived? If you
answer "no" then you are opening yourself up to the possibility that would
not survive the walk either. If you argue that the copy might be physiacally
the same but mentally different then you are saying there is some
non-physical basis to identity which survives walking but not teleportation,
which I suppose is possible, but there is no reason to believe that such a
strange thing would or could have evolved.
