Women are subject to meaningful rate limits. Ultimately the number of women determine the rate at which a population can reproduce.
A man can mate with many women, so eliminating a single man from the reproductive pool might have a significant impact. However, the women that man could impregnate might simply end up impregnated by someone else.
Not entirely sure how to model this.
I think that the argument from "avoiding coercion" is silly. First, because that isn't what literal coercion means. But moreover, At federal minimum wage, that money only takes 350 hours to earn. Over 18 years, thats 20 hours a year. If someone doesn't value being a parent enough to work an extra 23 minutes a week, then it doesn't seem like that is a right they value particularly highly. Also, there are laws that, taken together, coerce parents into working more than 23 minutes a week to support and care for their children. If we aren't willing to get rid of laws against child neglect, why are we worried about coercion in this case?
In contrast, an American man can decide to get a vasectomy at age 18 and, yeah, sure, we will do that. No problem.
I don't think denying men who are old enough to serve in the military the right to reproductive choice remedies the situation in any way.
Nonsense.
