Neils Bohr said similar things about elegance, parsimony, etc. So, I see the point, but IMHO you are over-interpereting or even misinterpreting "clear speech". You can climb the mountain and it may be arduous etc, but you still need to do it in baby steps. You don't get to climb it by leaping around behind bushes (however arduous that may be) and suggesting you climbed it anyway.
There is an alternate criticism of clear speech -- sometimes we have to stumble around blindly before we find the path to a result, often arriving at the result beforehand (I would suggest that this is how children learn things -- in their use -- but I don't want to go all Heidegger on Jerry at a point when we may actually be in agreement ;-)).
But once someone's been there, as a Manhattan socialite no less than Sandy Pittman, Doug Henwood should be able to call upon the sherpas to drag him up the damn hill ;-).
