Then I think I agree with you, mostly. If time or a similar limited resource makes rigorous justification too expensive, we shouldn't require it. But whatever we do accept should be minimally justified, even if it's just "I have no idea where to go so I'll pick at random".

I wouldn't look at the map if I were running from the boulder. But I would have looked at it before entering the temple, and you can bet I'd be trying very hard to retrace my steps on the way out, unless I thought I could identify a shortcut. Even then I might not take the gamble.
