Mary Shelley tried to warn us of this a long time ago.
No, she did not. Also, Nostradamus didn't predict Hitler or the September 11th attacks. As for the ethics of the issue, that's a tough one. I agree with you that there "may" be a black market for this, eventually. This isn't like getting a gunshot wound treated at a back-alley clinic. With proper regulations, it can be controlled in a safe, ethical manner.
