Cloned individual would not be considered an equal to the original. Child might not feel psychologically independent of the nucleus donor. People would compare the clone's performance in life with that of the nucleus donor. Assuming that a cloned child will be exactly like the nucleus donor assumes genetic determinism. Furthermore, clones would grow up in a completely different environment than its genetic predecessor.
Many people are psychologically dependent on their parents and other family members right now.
Furthermore, the more we clone people, the less diverse the human genome will be. This lack of diversity will make the human race especially susceptible to illness and disease. Many of these fears rest on a mistaken belief in genetic determinism. We should be opposed to eugenics, human experimentation and organ farming for their own reasons.
