I guess that's what "alignment" always comes down to? "Do what I want even if I can't tell you exactly what I want - because if I could, I could also just do the work myself"?
This doesn’t seem like an unreasonable requirement to me. People do this all the time?
Sure, a request might not always be perfectly unambiguous. But people can generally estimate pretty well whether someone making a request is expecting the agent fulfilling the request to commit a crime in order to fulfill the request.
