We teach people to do all kinds of things. We also teach people why not-to do all kinds of things. They do them anyway.

Furthermore, if all that is needed is the information in order to be able to do the thing, theres no absolute way to prevent every person from accessing that information and, thereby having the means to do what they’ve be taught not-to do. So, in your scenario, someone, sometime, will use the weapon despite know not-to.

That said, wishing a nuclear weapon into existence — the highly-enriched uranium, the implosion core, the triggering mechanism, and the delivery system needed — seems like a helluva waste when literally everything else is also within reach. I’d hope that intelligence would be needed to understand the process; and that same intelligence would be sufficient to understand the possibility of a thing is not reason to do a thing. There’s a very crude example coming up.

Personally, I think the command of matter-energy interconversion, higher-dimensions of reality, and cosmic-levels of power might inspire one to travel widely, live fearlessly, and create new possibilities. Petty grievances — those solvable with nuclear weapons — would seem like non-problems when literally everything else is not a problem either. No hunger, no cold, no lack of shelter, no distance too far, no need for authorities… just wish-fulfillment.

Summoning a nuke would be base, awkward to the point of being detrimental to all relations. It would be like a Supreme Court justice shitting in his own hands and deliberately smearing it on the faces of elders, kindergarteners, military service members, civil-rights activists, and puppies.

Like, ew. Who would do that?
