You pass laws than essentially make private investments subject to public control. Don't be surprised if there is less investment in infrastructure.

This is the most important reason why cloning of humans is completely unacceptable.

"cloning mammals by nuclear transfer is still highly inefficient, with Dolly the only lamb that survived to adulthood from 277 attempts"(http://en.wikipedia.org/wiki/Dolly_(sheep))

Is the company that does the cloning being open about this aspect of the procedure? If they are trying to pretend that they can evaluate the embryos created by nuclear transfer and only bring the least damaged ones to term, they are making a preposterous claim. The problem of evaluating a DNA sequence for all possible DNA damage is fantastically complicated, probably formally undecidable in the Alan Turning's terminology.

How many copies of these treasured pets are living a few pain-racked days in a laboratory?
