If teleportation is actually ever invented, it will work this way definitely, because it relies on the phenomenon of quantum teleportation.
So, let's see, if i use the teleporter, i die and an identical copy of me appears on the other end. In essence, i am the only one really affected by it because there's still a "me" in the lives of all the people i know. So in the end it comes down to whether i alone am comfortable with sacrificing my own life so that someone else who'd represent my identity can have a better life (due to the fact they can use the technology of teleportation). I'm pretty sure I'd do it.

It's kind of the same as euthanasia, in my opinion, anyone should at any point have the right to kill themselves, given they're deemed to be psychologically stable. We could psychologically test people as well in this hypothetical situation (for prolonged periods of time if that helps) and give them a "teleporter pass", if you will.
