I think this is one of those wordcel arguments that sounds nice but probably has no bearing on actual reality.
If we live in a world where human effort has no marginal utility, we also live in a world where human life has no value. If we don't, you're in a world where you're competing with other humans for some set of resources. Regardless of whether you believe that you are competing with them, others are competing with you.
I think competition is perhaps one of the most basic rules of reality.
Focus on automatisation and we don't have a production issue.
Its a man made problem, not some kind of magic rule.
