I...no; no, that's not how that works.

If I were saying "everyone needs to go to a restaurant on a regular basis," then it would be hard to justify me also calling going to a restaurant a luxury. But that's not what I said.

What everyone needs is some luxury in their life. Something that's not just there to keep you alive—something to make life worth living.

Having luxuries sometimes is what separates surviving from thriving. And yes, everyone—everyone, no matter their station in life, their choices, their income, whatever—needs and deserves to thrive.

You're confusing the definition of a singular thing with the group of things.

For example, apples are a luxury in that nobody needs them to live (and the same can be said of any single food source - and therefore whether or not we consider something a luxury comes down to its availability and cost, nothing to do with champagne being more or less "needed" than beer), but they are also part of a bigger group we call "food" that definitely is not a luxury.
