You are right this is practically and theoretically impossible: The no-cloning theorem tells you that it is impossible to “copy” a quantum system. So it will never be possible to create an atomistic copy of a human. Technologically we are of course also miles away from even recovering a complete connectome and I don’t think anyone knows how much other state would be needed to do a “good enough” simulation.
