Since that's nearly certainly less efficient at population expansion compared to physical violence. Conservatively, modern humans seem to settle at having 2~4 children per woman but historically it was not uncommon to have families of size exceeding 10.

The whole point is that if you accept the fact that expanding population is good a priori, this leads to stupid conclusions by the tyranny of exponential growth. Who cares if the average person is a slave when you have several hundred billion of them. Who cares if mothers die horribly after being forced to carry child after child.

Personally I think the only consistent viewpoint is some form of logarithmic population * average well being metric to measure utility. From that perspective, I have no clue how a policy maker should act today. Hopefully smarter minds than mine figure it out!
