One of the major ways this point is driven home in real life is through... letting the person fail in their task, suffer the consequences, and hopefully remember to read the goddamn manual the next time. Of course then there's a failure mode of e.g. bureaucracy, where people know everything is in the "manual" somewhere, they just don't trust themselves to understand it.
In this case though it's "you failed! try again tomorrow!" (because it's a daily thing). The odds I'm gonna come back tomorrow are extremely low though.
“Morally”, no we don’t. (Me included.)
Say, if you are a games designer and want to get the message across, then you can start A/B testing ways to get your point (pun mostly not intended) across more effectively.
