We need to think about all of the modern techniques available to us in terms of how they can enhance life rather than control it. Cloning seems made for therapeutic reasons. If a person is missing a part of the body and it can be duplicated and reattached, then that seems like a wise use of this modern technology.
Consider debilitating diseases such as Alzheimer's, cystic fibrosis and multiple sclerosis when modern medicine looks to therapeutic cloning for cures. Although not a panacea, cloning human bodies for specific therapies that can't be cured by normal means should be a viable way to save lives and extend life for several decades. Congenital defects and diseases are another way therapeutic clones can be used. Growing healthy tissues and organs from clones shouldn't be a big deal, as long as the bodies aren't brought to life with fully realized nervous systems.
