In our bizarro world of unintended (but predictable) consequences, this is what would probably happen. I can also see those regretting taking such action and demand the government facilitate them having children somehow, maybe through government funded IVF farms or surrogacy. Nothing is beyond imagination in this insane Brave New World that Progressives have frankensteined into existence.
Or indoctrinate our kids in the public education system.
And as technology advances, expect them to be able to “make” babies in a lab. Maybe from tissue such as skin. No longer need the egg and sperm. There are no restraints and we cannot trust them to chose ethically. Especially, when they claim that a human being is just a lump of cells from conception to 9 months in the womb and completely viable. There are doctors happily participating and they are supposed to be governed by “do no harm.”
