Indeed, objects should have been larger. As large as a module. Perhaps with interfaces implemented by different concrete modules. Like non-oo programming language were doing, circa late 80s [modula 3, sml]. While at that, “message passing” [aka goto with arguments] is too fine grained of a concept, what people need 99% of the time is a structured function call.
