Those are simply incidents where the scaffold foothold temporarily slips. A true counterexample is pure interaction without words, akin to what dogs and other animals do (excepting things like recognizing their name), or meditative state where the conscious mind is no longer driving. Words provide an information-space regularity mapping to similar constructs in other minds, a shared "game" with shared (crowdsourced) rules. This, in turns, allows the cognitive chunking of words/ideas mappings so that they can in turn be used as constructs within larger intentional chunks, largely automated by your brain machinery, so that you don't even have to be aware of the syntax, only the semantics. A world without words would be like navigating in an ocean without lighthouses and stars: anything is possible, but you never really know where you are and where anything else is (including others' minds)
