That is job of society as a whole to decide. Much as we decide speed limits, drug offenses, food labeling, clean air restrictions, etc.
For all of those who fear government, it certainly has a place here. I don't think unregulated corporate control of genetics, cloning technologies, reproductive technologies, cloned in vitro food production (vat meat), GMO crops, et al is a great idea for society.
At this point in my life, I sorely regret not going into grad school in genetics when I graduated from college. The applications, and implications are incredible. There is so much that they know and can do now compared to when I graduated from college. The biological sciences, particularly the spheres of biochemistry and genetics, have made enormous strides in the last 20-30 years.
As I said, the laws are lagging the science. We will have the technology to clone a human being long before we have decided if it is a good idea or not. There are so many questions brought up by science. We are reluctant to deal with them. They are often difficult for the non-scientist to follow, many of those in position to make the laws are uncomfortable with both the science and the moral issues. Many of the positions that lawmakers will eventually be forced to face will cause conflicts with both donors and constituents.
