Personally, I think it makes more sense to look at D&D holistically. If all someone wants to do is criticize the lack of narrative rules in the ruleset, okay. It hasn't stopped people from running narratively focused games and enjoying the experience.
Sure, a different game might be a better "script". I never suggested otherwise.
In an earlier post, I compared D&D to a multi tool and bespoke games to a set of screwdrivers. If what you want to do is drive a bunch of different screws, then obviously the screwdrivers are the way to go. However, if you want to carry a tool around with you that's good, but not ideal, for a lot of different jobs, you take the multi tool. The multi tool has different utility than the set of screwdrivers. Criticizing it as not being a good screwdriver might technically be accurate, but I would say it's missing the forest for the trees.
