AgreedI agree that the amount of children he has should not be commensurate with the amount of sperm he produces. But even as in agriculture, not every seed produces fruit, and spacing is critical to the plants growth.
I also agree that not every man will be a polygynist. There are enough men in jail, gay, MGTOW, players, and "trans" to create an imbalance in ratio of godly men to christian seeking women. The church is filled with single women and single moms that are left out in the cold, that those of us who COULD take them on, and want to, should be allowed to.
I think we are on the same page, there just seems to be differences in how we view it's practicality.
In my situation, about 6-10 would be ideal.
Most men probably won't (and likely shouldn't) be polygamists. Some men however probably should have multiple wives. A lot of good women could benefit from polygyny. Men and women deserve to have the option of polygyny (since God gives it).
