I agree completely! And this shows up in just about any language because of that — however — I kinda get where the author is coming from. When a certain amount of state is encapsulated within a single actor (or a single message for that matter) you can act on all of it sorta transactionally since no other actor has access. This is probably more power/control than some programers have had in other languages or paradigms. Your full program state dosn't retain this property once it spans actors but what can ya do.
