While fundamentalist churches have obvious problems with whole-body cloning, they have said little so far about this process. This is not a matter of someone producing other human beings. It is a person producing new organs from his own body to save his life. But, to repeat, somebody has to get in the way of this. Liberals cannot allow any productive endeavor to go ahead without their having control over it.
Liberalism does nothing productive.
All it does is to regulate productive people. By the same token, liberalism cannot allow productive people to go ahead with what they are doing without regulation. But in the case of scientific advances in dealing with human beings, liberals are in a bad position. This is not a matter of income redistribution or of defining education. This is a matter of ethics.
