Not really. The author is using the common definition of the word, not the clinical diagnosis. She made that plain.

She means it as being entitled and how that informs one's personality and view of the world. And that fits.

Our social organization is a dominance hierarchy. You can't have that without the higher levels being entitled to things from those lower on the totem pole.

Like how men objectifying women makes them entitled to women's time and attention, sex, they seek and desire fawning admiration from women to validate their manhood, women are seen as resources not people, women are an afterthought most of the time (like medical research example), etc.

All of these things are acts and attitudes couched in a narcissistic mental framework that is an inevitable dynamic of dominance hierarchy.
