>The copy was brought into existence without its consent

This may surprise you but EVERYONE is brought into existence without consent. At least the pre-copy state of the copy agreed to be copied.

It obviously doesn't surprise me because I specifically mentioned babies.

I'd also be interested in your moral distinction between having children and cloning consciousness (in particular in a world where the latter doesn't result in inevitable exploitation, a loss of human rights etc.) then.

Typically, real humans have some agency on their own existence.

A simulated human is entirely at the mercy of the simulator; it is essentially a slave. As a society, we have decided that slavery is illegal for real humans; what would distinguish simulated humans from that?
