I'm not asking for a debate. I'm simply asking you to tell me what "exactly once delivery" actually means in a way that isn't circular and doesn't beg the question of whether or not it is possible, i.e. the definition that is used in literally all of distributed systems research. So far no one has been able to do that.
I don't want to get into a debate over semantics with you. You've redefined exactly once delivery to mean that if you have a layer of abstraction that hides that a message was delivered multiple times then it is "exactly once" delivery. That's not what exactly once delivery is. You clearly disagree but taking well understood and researched terms and redefining them to make a point is a complete waste of time for everyone. Nobody cares about what your personal definition of exactly once delivery is, they care about the definition that is used in literally all of distributed systems research.
