What this highlights is that online we have lost - or at least eroded - social norms. If I see a sign that says "no vehicles allowed", it's obvious they don't mean wagons and strollers. In almost all cases the police and the public are 99% in sync. Online, though, the moderators are forced to do a careful study of every action and become asinine literalists lest a horde of boundary-pushers ruin it for everyone.
I think what it highlights is that the meaning of words depends on context and stripping all context from a rule and situation makes that ambiguous. Reading more into it than that seems silly.
Even simple things like chairs, you can't write down a definition that includes everything that humans consider chairs and excludes everything humans don't consider chairs.
