Should Human cloning should be permitted

[Rodri]

The meat-locker clone for spare parts? Forget the immorality of it and think about this.

Your clone would have the same genes as you, so if you are genetically prone heart disease or cancer etc, so is your clone. Your clone will also be lacking the disease resistance that you have built up over a lifetime and could be killed by something we think of as minor, such as measles.
Is your clone going to be kept unconscious? Then it would be weak like a new born baby or even worse, as muscles that are not used regularly tend to atrophy.

So these things can be overcome by letting your clone live a full and normal life right?
Yes they can but what does that mean in moral terms when you need to harvest those spare parts? Or what happens if your clone becomes a drug taking s3x addict who enjoys adventure sports such as base jumping? Do you have the right to control your clone's life so that they don't put your spare parts at risk? If so, is your clone now your property (slave)?

What if your clone develops kidney disease? Would you be willing to give a kidney to help keep your spare parts alive? If so, which one is spare parts for which? After all, your clone just harvested one of your kidneys. (maybe you are the clone and they are the original?)

So you become ill and need to harvest some parts to survive. The parts you need means that your clone will not survive. Now what happens if you get sick again and need some more parts? Easy, more clones, right? So how many clones is a safe number to have for organ harvesting and, more importantly, who is going to pay for their upkeep, so they are nice and fit and healthy when you need those parts? Can you afford to pay for maybe three or four clones?
Then what about your children? (if you ever have any) Are you prepared to pay for three or four clones for each of your children so that they can have spare parts available as well? Remember, they need to be kept healthy and active or those spare parts won't be in tip-top condition. I am thinking it would take a very large fortune to be able to look after all these clones.

Now here is the last question I will ask.
You have your three or four clones that are all nice and healthy but you die in a car crash and no amount of spare parts can bring you back to life. What happens to your clones now? They were only created for spare parts, so do they get to live out their lives or do they need to be killed? If they get to live, what happens if one of them gets sick? Does it now have the right to harvest parts from any other surviving clones?

I sometimes wonder if these big ideas such as cloning for spare parts ever get fully thought through.
