I agree that it's an important difference! And it matters a lot. I am just saying that the concept of "copies" is no more mysterious than the concept of "superposition", and if you can accept the latter then I don't see why you complain about the former. As for collapse, Copenhagenists can't seem to explain why an interaction between a photon and electrons in a polarizing filter does not collapse the wave function, but an interaction between a photon and electrons in my retina does. They're made of the same stuff and should be following the same quantum rules; why does one of them perform a unitary transformation and the other a lossy projection?

The reason I can accept superposition is that I have first-hand access to experimental evidence of it. I can see interference fringes with my own eyes. By way of contrast, not only do I not have any direct evidence of the existence of copies of me, I cannot possibly have such evidence. And this is not a technological limitation. This is a limit predicted by the theory itself.
