The assumption that all users know what all processes, tools, or facilities are doing, at all times, and at all instances, has proved false far too many times.

You could argue that the user should know what they're doing, but then, drivers shouldn't crash cars, and pilots shouldn't crash aircraft.

Numerous elements of this problem are simply hard, perhaps impossible to resolve. If the problem is what Neal Stephonson called metaphor shear in "In the Beginning Was the Command Line", then the fundamental problem isn't technical, but that people generally are operating under a false mental model of what computers are, can do, and do behave.

Yes, "all models are false, some are useful". The utility of this one may be past its sell-by date.
