Luxury means "something expensive which is pleasant to have but is not really necessary". My anecdotes were trying to show that they're not really necessary, and the sibling comment further explained that individual bedrooms is a relatively recent phenomenon for the majority. It's fine to prioritize individual bedrooms if that's important to them for some reason, but it's important to keep a realistic view of things, too. When things become common, then people sometimes forget that the less expensive option is totally acceptable, and means fewer years spent needing to work, more financial freedom, lower financial stress, etc.
