How is limiting family size not a higher end?

Limiting family size is only necessary when a new member of the family would prevent the existing family from obtaining necessary means of survival.

Assuming that these conditions obtain, family size can be limited by taking advantage of the natural periods of infertility which are an integral part of the natural generative faculty or through voluntary abstention - both of which preserve the physical integrity of the person and their faculties.

Limiting family size is only necessary when a new member of the family would prevent the existing family from obtaining necessary means of survival.

So survival is the only "higher end"?
