Often I find in these discussions that people want to define a "dissociated mechanic" as meaning something other than what I defined it to mean. Then they'll argue against their definition. Which would be fine, I guess. But then they'll claim that they've actually said something meaningful about the concept of "dissociated mechanics" as I originally defined it. But all they've really done is construct a strawman.
In my experience it's the people trying to use the term that way who define it. And then exploration indicates they mean what I'm talking about. I have different issues with the way you defined it than the way it's commonly defined.
The topic of hit points in these discussions is usually more misleading than enlightening: Prior to 4E, there was an interpretation of hit points (supported by most editions of D&D) which was associated but heavily abstracted. (And that abstraction was possessed of variable flaws depending on which edition we're talking about.)
This, I believe, is historical revisionism. 1e is emphatic in defining hit points as skill, luck, stamina, and divine protection - and out and out says that the meat definition is ludicrous. Entirely compatable with 4e. 2e on the other hand indicates that they are meat. 3e ducks the whole question quite neatly. And 4e almost entirely agrees with 1e but gives a second axis of lont term stamina.
