This is silly. Having kids is absurdly expensive*, and you STILL have to parent them somewhat. You can’t just pop out a baby and have it be fine 30 years later if you don’t touch it. Even if the impact of the outcome of each child on each other child is marginal, the impact on YOU is still large.
The argument is not that kids are costless, but that people overestimate the cost of having kids. If you don’t get much utility from kids then this isn’t going to sway you, but if you like kids enough to have one or two, this might make your life easier or convince you to have more kids than you otherwise would.
