There is no "truth" about what necessities and luxuries are. Put any of our great-grandparents' families in a time machine and their children would now be taken away for neglect. For everything you own, somebody out there thinks it's a self-indulgent luxury you'd be better off without. What gets taxed as a "luxury" would become a political decision, which is a game the rich know how to win. Have you heard why SUVs suddenly became popular? Somebody figured out trucks over a certain weight limit were classified as business necessities with favorable tax treatment.
