Some of the problems I imagine...

Isn’t a cloned person another human being? Harvesting organs would be murder.

Cloning everyone? Sexual reproduction is nature’s way of adapting to changing conditions on the Earth. Short circuiting that process is potentially disastrous.

Cloning genius? Only possible if the exact environmental influences can be reproduced. Different synaptic connections different results.

Who decides what a birth defect is? What if skin color became a legally defined birth defect? What if having just 2 hands became a defect? Would this open the door to the creation of humans with extra appendages or body types for increasing production in corporate sweatshops. Think of the potential misery of these engineered humans. Would brain power be diminished to avoid this misery? Would these creatures be disposable?

Some even more speculative thoughts...

Could this be a way to validate the existence of the soul? What if a soul is forced to return to its cloned body? Does spiritual evolution cease?

What if a clone has no soul?

If a new soul takes up residence in a cloned body then you have a new human life that only appears to be the original on the outside.

So many possibilities for unintended consequences.
