It's hard to penetrate to the heart of the matter, because I'm not sure what you are saying.
> Other person: "I like these very common qualities about housing that many other people also like. This is proved by the fact that houses with all these qualities have much higher demand and price".
That's backwards. The other commenter was saying their home was less expensive and larger than what was in NYC, and therefore superior.
> we can just generalize things based on obvious and common preferences
We can't truly say something is better or worse without some scale on which to measure it. Is a Macbook or cloud Linux instance better? It depends on what we want to do with it - graphic design? Macbook. Host some files publicly? The Linux instance. In other cases it depends on the user - a veteran Linux sysop may use their favorite OS for more things, an Apple guru will prefer theirs.
For some things almost everyone shares the same scale and generalizations are accurate. We could generalize that people prefer running water, heat (as needed), roofs that don't leak, larger spaces (to some limit), lower costs, etc.
But for other things people have different scales and then generalization is false. In this case, preferences for location vary widely; some want NYC because on their scales, it scores really high; some want quiet suburbs, based on their scales; some want rural or small town, warm climate or four seasons, etc. The other commenter seemed to assert that their scales/preferences were universal, and I disagree.
IMHO the best part of human interaction is learning about people and points of view I don't already know - I learn infinitely more than hearing myself talk or by framing their points of view in my perspective; that limits what they say to what I already know, like a someone insisting mathematics be described only in English words they already know - they need to learn new words and use some actual math, or they are limiting themselves. The other commenter seemed maybe to think it was a fight (I don't want to speak for them), so we didn't get far.
> you are playing a word game that ignores anything that actually matters
It seems like you're saying that the other person's ideas are games, and yours are the only ones that actually matter. If you notice I'm not addressing your ideas, you might be right, but not because I'm playing games - I actually have different ideas. My ideas aren't measured by how much they agree with yours - I use a different scale in that case.
Those are the very best chances to learn in life, IME - an opportunity to open territory I didn't even know existed 5 minutes before. If I am curious and interested (and I genuinely am), I find that almost everyone has very interesting, valuable things to say. You too.
I think I'm signing off, as this thread isn't yielding much of that sort.
