The writer's put limits on the transporter, otherwise nobody could actually die in Trek. If they can use the pattern in the buffer to restore someone to a previous condition, (as has been done since the animated series) why would someone recently dead be an issue? It's all just molecules.

There's a similar issue with Genesis.

Whether the transporter is actually killing you and copying you all the time is an even more creepy issue.

One detail that's bugged me since TWOK is people talking and moving while being beamed.
