I'm fine with you calling sliced bread a luxury because it reminds you of how nice your life is compared to 'nasty, brutish and short'. What I wouldn't be fine with is you reading a car advert on HN talking about luxury climate control and posting "How dare you use the word 'luxury', luxury was solved with sliced bread, now you're moving the goal posts and it's not fair!".
And then you posting that again when reading about a luxury hotel, and posting that again when reading about a luxury cruise, and posting it again when reading about a luxury concierge service, and constantly reminding everyone that "luxury was solved with sliced bread and that's all anyone ever wanted from luxury and when people in Biblical times dreamed of an afterlife of luxury with no work and no suffering, what they actually wanted was sliced bread and don't you dare suggest that luxury ever meant otherwise".
