Have a look at the opening segment (video below) of this episode of The Big Bang Theory. I've had exactly the same conversation about teleportation (or transporters on Star Trek) more times than I can count. Sheldon (taller guy, on the left in the picture) is the theorist and Leonard is the experimentalist, both at Caltech.
On teleportation from A to B: let's reverse the time ordering of steps and see if it bothers you. If I were to first produce an exact replica of you at the desired location B, would you then be willing to step into a disintegration chamber at A?

Another bit of dialog from the episode; Rajnesh is an astrophysicist.
Rajnesh Koothrappali: Do you know what he (Sheldon) did? He watched me work for 10 minutes, and then started to design a simple piece of software that could replace me.
Leonard Hofstadter: Is that even possible?
Rajnesh Koothrappali: As it turns out, yes.
