In the unlikely event that a worldwide ban were enacted it would be easy to do the cloning aboard ships in international waters. Having the ability to clone people, together with the associated technologies of genetics, has such immense potential advantages that any country which might ban this technology would be resigning itself to second class citizenship in the scientific world. If the United States fails to lead, many other nations have enough knowledge and resources to develop this new resource. The U.S. Congress's attempts to ban cloning remind one of an ostrich burying its head in the sand at the approach of a tiger, thinking that if it cannot see the tiger, the tiger is not there. We know the tiger is there.
Cloning adds a burden of responsibility.
We have a new genie and we must think of the right wishes. Trying to put the genie back in the bottle is not an intelligent course of action. It is also impossible. We find this to be a most curious if not outright ridiculous idea. It reminds me of the attitude in the Royal Navy discouraging innovation in the building of ships in the early 1800's, one result being that French ships were often of superior construction.
