Hmmmmmm...I think there has been a cultural shift toward an optimization of one's connections to only include a memetically-purified ingroup based around one's existing beliefs.
I think there is a danger in toolbox thinking BECOMING law thinking without the due diligence required to justify the law outside its original context.
I.E. an obsolete mode of lawful thought is superceded using a tool, and that tool becomes the new soon-to-be-obsolete mode of lawful thought, until a new tool solves the contradiction... and becomes its own new lawful mode. Sort of a Hegelian dialectical process.
I.E. Progresses are stupid, but they work anyway.
"Among my readers, there may be some who presently assert—though I hope to persuade them otherwise—that the life of a child is of no value to them. If so, they may substitute anything else that they prefer, at the end of the switch, and ask if they should press the button."

But for real, why assume your readers have human terminal goals? There is certainly an ever-increasing probability that your readers include AIs made to do all manner of things, and their terminal goals are only bounded by who would write an AI capable of reading your posts and what motives they might give it.
And keep in mind they may not give it motives they have. Indeed, from an AI safety standpoint, making narrow AIs or very weak General AIs with deliberately bad goals is useful to understand how they behave and can be altered. And considering that current approaches involve vast amounts of training data, and AI safety researchers have a high likelihood of using your posts as training data, I would say odds are multiple of your readers DEFINITELY do not value human children whatsoever and have only knowledge of what a human child is as a linguistic construct.
