That's not how cloning works. Clones aren't empty husks full of free organs ripe for the taking, any more than non-clones are. Even if you could create a clone without a brain, it's still hard to condone. If an anencephalic fetus miraculously grew to 24 years of age, would people post a "free organs" sign on him and lay him down on their lawn? Gonna have to say... probably not.
