Question

The above series depicts a situation in which the world is suffering from enormous fertility problems, and very few women (and men) are able to become pregnant (or impregnate someone). As a result, a regime arises that wants to rehabilitate the world and increase the number of children, etc., and so it takes all the women who are able to give birth and enslaves them for reproductive purposes. {The series deals with the fact that the government takes for itself many additional powers that go beyond this idea, and in practice it is corrupt and does not have only pure intentions, etc., but that is not really related to the core of the issue.} The question is whether, in such a situation, where there is basically no childbirth in the world and no people left (there are descriptions there like, “No child has been born in Mexico for 9 years,” or something like that), would the proper thing not be to enslave women for these purposes?
In other words, where the rights and freedoms of the individual clash with the desires and welfare of the general public, how does one decide, and which takes precedence over which?
