I had a similar argument with a friend, and I think he won that time. It came out of left field and rephrases the whole thought experiment.
Instead of me defending the argument, how would you interpret a clone incident? Would you get 'the other feed' as well? We have the sleep cycle where we don't actively get input (even though our conciousness is present during dreams to a certain extent). So if a transporter clone incident rebuilds the person on the other side, but an original instant could go on experiencing a life that wouldn't be if the transporter functioned correctly.
Hopefully that took the soul out of your argument!
Well, teleporting is more like the move function where you delete the original copy.
