To be clear, I don't think what
@kenada (or
@pemerton or
@AbdulAlhazred ) are concerned with is (a) whether JA has "a bit of a messiah complex" or (b) whether "his intent is to suggest that you must follow his rules at all times" or (c) whether there is advice that is going to be appropriate for all the ways to play D&D.
The interest is a very narrow one:
Does the chokepoint-averting impact on play that The Three Clue provides implicate pre-authored plot being funneled to?
My answer to that is "yes." And I don't think the breaking part of events in that kind of game into
plot point > diversion of freeplay and/or benign color and/or book-keeping (like "taverning" or pastry-baking or selecting spells during rest or spending coin at the market to reprovision or whatever) > plot point > plot point > diversion of side quest > plot point > diversion of freeplay and/or benign color and/or book-keeping > plot point is relevant to the question. That is because
the trajectory of consequential play is pre-authored (the mystery) and is funneled to via the chokepoint-averting Three Clues (or whatever value).
