In reality, the act of producing more population is a singularity in terms of scarcity.

Imagine we are in a bitcoin standard. Every added person should add exponentially to its network effect.

When a thing is perceived as scarce, it increases in value and people produce more of it because they think it will give them more wealth (in this case by giving them more money).

When a thing is perceived as non-scarce, people focus their energy on better profiles of opportunity cost

All of this doesn't occur in human reproduction. When society produces more humans, it would increase the exponential effect of Bitcoin, making everyone in the planet stupidly richer. This means there's a direct incentive for every human in the planet to reproduce more and more because doing the exact same action will make everyone more and more wealthy in an asymmetric fashion, a thing that is unnatural in every other mean of production
