That's the issue here. The door that Rifkin is possibly referring to is the patent that would remain once the baby is full grown. But Geron, the company that owns the patent, has insisted vehemently that it does not wish to clone human beings. Images of organ farms quickly pass through people's minds when such ideas are proposed. Again, the answer is pure economic interests.
Patents protect competing companies from stealing ideas in the field of genetic engineering.
It is a necessary situation if society is to embrace this new technology. Without patents and regulations, a field cannot expand. Of course, much of the populous of the United States do not want to see such technology expand. No longer shall the touch of God heal those jubilous participants of Christ's congregation. Instead, let the future organ evangelist farm you a joint free of arthritis.
