Can saying "death has no subject it occurs to" be defined as a category mistake? You seem to attribute to death, by your construction, that it has anthropic properties, or sentience and maleficence of some kind. Death is not a person, but a state, one which befalls each of us. How do we say X 'is' dead if they are not X? By your argument, we ought not to attend funerals for the deceased we know...oops, we can't know them if they no longer are whom they were prior to (their) deaths. Funerals are out because they are about death, and not the dead.
Once again, death does no depriving. It simply is, it becomes, just as those who live become...dead.
You say, "A wrecked car is simply a wrecked car. It is not a car." Wrong, it is only a wreck...just like all other wrecks that are not what they were prior to the wrecking. At least, as I understand you, that is what you are using for logic. There are no dead people, just dead, or The Dead. So, we can group rotting corpses of all kinds and species, The Dead, into one broad category, indistinguishable. We can't talk of The Dead because they have no identity and therefor no names are useful. We might talk of the memories of The Departed, but we can't call them human, men or women, and not even distinguish between those advanced in age and those who died during childbirth.
To me, a misfortune is something you endure, consciously, for which you must suffer to some extent. We don't suffer death. We experience it while it is happening, however fleetingly or prolonged the experience may be, but when we actually die, when we 'get' death, we don't know it (stories of bright lights and voices notwithstanding). We lose consciousness and die, and the rest is really irrelevant, be it bodily damage, autopsy, dragging by heels through the streets, hanged, quartered, drawn, head displayed on a spike...it's nothing like a misfortune to the dead 'person'. To that person's loved ones, well that's another matter.
