[General] Is there any piece of fiction where teleporters are only used in absolutely crucial scenarios?

Now, I'm thinking of the old fashioned version of teleporters where they disassemble your molecules and rearrange them somewhere else. And in this process....we'll you're going to die, no way around that. What comes out on the other side is essentially just a perfect clone of who went in.

Now, is there any fictional setting that actually pays attention to this and treats it as an actual worry? Where if you want to teleport you know that where you need to go is worth your life.

I remember a short story that did this really well.  Only data could go faster than light.  So they basically teleported a person to another planet to learn for 20 years.  

The main character was the technician who had to push the button to "dispose" of the original.   The aliens who brought the tech didn't understand our problems with it.  For them the original would just commit suicide to balance the equation.  

One day there was a glitch.  They didn't get the confirmation notice right away.  The original had left and wouldn't go back into the room.  So the main character pushed her out the airlock.
