>> Suppose I take two atoms of helium-4 in a balloon, and swap their locations via teleportation.

For a book version, you will definitely want to be more precise here. I assumed they were in different quantum states (this seems a very reasonable assumption failing a specification to the contrary). Perhaps they had different spins, energies, momenta, etc. This means that the swapping *did* make sense.
