Here's another question: "How can a human being, which consists of many neurons, each of which has limited agency over the aggregate actions of that entity, be remotely capable of demonstrating moral agency?"
Incidentally, I noticed that you substituted 'human-like moral agency' for 'moral agency' in the OP. I never said states have human-like moral agency (nor am I making a claim to the contrary per se).
No it's a rhetorical question, turn it into one with an answer and you'd have rebutted the argument.
You might also note that the answer to your question is that they don't. It is a problem applicable at scale - and we do terrible things to single neurons all the time in the name of science.
