I think this brings us closer to an understanding. Dungeon World repeatedly admonishes the participants, especially the GM, to speak to the characters. Also to speak as the NPCs. Thus you ask "Thor, what are trying to do here?" Not "John, what do you want Thor to do?" This is exactly what
@Campbell is talking about in the post you quoted. The players don't have desires within the fiction! They're advocates for their characters, but they don't steer the fiction. The game is about playing out what the characters think, feel, and do. This ties back to me saying that the GM is not really 'the opposition' either. DW then has a separate channel for what the players want to see in play, answering questions about the setting and situation, and at the mechanical level of play.
