Quantum teleportation means, in a seriously tiny nutshell, that a particle X can be recreated in another place. So if Kirk got into a quantum teleporter, he himself would not appear at the other end, only an exact copy, duplicated down to the state of individual particles. Theoretically, the copy could even be thinking the same thoughts as the original. But it’s not the original that makes the journey, just a copy. And it can’t actually be done with anything large at this point.
Not to mention that the particles to be duplicated must ALSO exist at the destination site, ready for assembly. (Note: not RE-assembly, just regular old assembly.)
Regular Star Trek transporters are no better than magic, because they do not exist at all in the real world we live in. In those, the original is teleported to its destination, not a fake.
Hence, the disappointment, and the irony at the end.
