This was clearly a response to the idea that logistics aren't.
You are missing the point.
The point is that, in "realistic" depictions, logistics should be a separate function.
In a situation of real risk, the party would hire a quartermaster to handle logistics for them, because Gorm the Gormless knows cleaving, not accounting. But the quartermaster would stay back at the inn, not be out on the front lines of the action killing the enemy!
D&D isn't a game in which you play the Quartermasters.
