Exactly. What if there's a bug and when your "copy" is created at destination original is not destroyed? Would you agree to be killed, should your copy agree instead? Even worse, what if there's an anomaly in transporting data, original is destroyed and copy emerges disfigured, dead or something in between? Teleportation scares the shit out of me.
I mean, cloning things has its advantages too. Could be a good idea for some people to deliberate screw up the process and drastically cut down on their daily workload. Or perhaps as a way for the less ethical to not kill or work alongside their accidental copies, but ship 'em off to join the army or something.
Teleportation going wrong can be just as exciting as prospect as it working out fine. Cloning has a lot of useful applications as well.
