Accelerated growth does not need to have any Ill effects, but those people will be still as old as their physical age. so if the woman grows into adult size in 4 years she will be still 4 years by humans standards and she may only barely learn to speak in that time.

I find it a bit strange that many dolcet focused forums complain about lolis but have no problems that they own characters are only 4 years old or so, what could count as toddlercon :)
and it is not very likely that those women will be very useful work force at that age


impregnation rate is not that important because it is not reasonable for a man to consume that amount of meat unless you only take some small part and throw away the rest what would be terribly wasteful
maybe you could somewhat recycle it by feeding it to other women as good protein source making then grow faster

But in any case, it would require an enormous amount of vegetarian food to grow that amount of women and low-efficiency manual labor would not be able to sustain that so life would be pretty hard for those men and totally pointless. cannibalism is a prety bad idea as the source of food.

But the main point of dolcet society is disposability of women where they have absolutely no value it is not about breeding them for food or eating it is more like you just have that many women that you need to get rid of them somehow
