C’mon now, let’s not be intentionally obtuse to try and sound smart adding “yes, but” to a perfectly solid argument. Children are easily produced, that’s a fact. The process of child bearing is not in question, but rather the availability of willing partners (hell, even unwilling, if we’re getting that dark) and how little effort it generally takes to get the conception process going.

They were making a point that it’s much easier to generate a human being than it is actually generating economically meaningful value. One needs a few minutes of your time and gets you feeling really good at the end of the process, and the other can (and often does) require years of effort, toil and sweat (all of which can catastrophically fail rendering your efforts moot).

Generating a new human is, indeed, comparatively easy.
