That's a question, not an argument.

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).
