one doesn't track who is going to conceive a child beforehand, one uses carrots and sticks as needed once the child is born and allows the rest of the population to modify their behaviour accordingly.

(ironically in the context of this response, a system used with great success by china to enforce their one-child policy at the end of the last century without anywhere near the level of tracking which is commonplace in most countries today.)

You think we don’t already have that kind of tracking? We have cameras tracking cars on almost every major road. We have at least half a dozen devices in every home potentially spying on every word we say, 1984 style. For shit’s sake, major tech companies are helping government officials track who is going to abortion clinics.

We also still have doctors forcibly sterilizing minorities. We don’t have a society healthy enough to limit parenthood.
