I think that in the bold, emphasis mine, you are laying your thumb on the scale a bit too heavily, which is a distracting detriment to the overall point you are trying to make.
Fair. I'll edit that.
EDIT-
The reason for this post is I was reflecting on what I see as a certain tension, if not irony, that underlies a few discussions. D&D, from the beginning to 5e's emphasis on "rulings, not rules," is a game that cries out to be FK, to be a game of players doing whatever they want with a neutral referee providing the results ... yet ends up encumbered by rules, cruft, and debates about RAW. As a reaction to this, you have many excellent games that arose from a different context- but instead of using the high-trust model of FK, they instead use various ways (either through explicit rules or norms) to create FK-like experiences that bind the referee.
