It is not clear if we should characterize teleportation of macro-sized objects as being impossible. It is extremely more complicated than teleporting a subatomic particle. Teleportation of a particle, actually, is communication about the state of the particle. The receiver takes that information and modifies the state of a local particle to be in the same state as the original particle. In macro-sized objects, each macro-sized objects has billions of sub-atomic particles. Communicating the state of each sub-atomic particle, and recreating the state of each sub-atomic particle at the receiver would be prohibitively expensive.
