The ethics of it are dubious because every time you see someone transport they are being literally killed in front of your eyes and a new copy created elsewhere.

They “nuh-uh’d” this in Enterprise. The inventor of the technology is introduced and basically says the people who propagate that theory are a constant thorn in his side, despite having no basis for it in the reality of that universe.

They also show people experiencing, and reacting to other things, in the matter streams during longer transports. Kind of hard to do if you’re dead.
