For that to matter, atoms would have to be unique. But an identical atom is literally identical. A transported you wouldn’t be any different than a printed you.

For that to matter, atoms would have to be unique. But an identical atom is literally identical. A transported you wouldn’t be any different than a printed you. I rather suspect that “you” are simply information. If that information is copied, there’s another you—at least for the instant before that “you” starts having its own thoughts and receives information through its own senses. For you to die on transport and “someone else” to come out the other side, you’d have to exist in some way separate from your physical self; which might suggest you can survive death anyway.
