Well, if the technology actually existed, it would solve that whole "soul" question.
We would know pretty quickly if we transported humans and they came out the other side as soulless aberrations because their original just got killed.
So yeah, I would 100% use it after it first proved once and for all that the sum of our consciousness really is all the synapses and signals and grey matter in our heads. Because if so then what does it matter if your original matter has been erased and then recreated. Your clone is just as much you as you are you at that point.
