You cannot separate the good and the bad effects of any development. Cloning research is funded by businesses who see economic gain in making the technology possible. The pharmaceuticals are the first industry to show an interest. Just because we think that we know what we are doing does not mean that we are able to predict the consequences.
Accidents are unavoidable in complex systems.
For example, bottle necking could be a problem. Perhaps the scientists will see such hazards and find a way to circumvent them. When we produce something we claim ownership of that object. There may be a difference in that this is a living organism, but already there are companies who own synthetically created life. If big industry is investing, they expect a return.
