It's not a win for you then. It is a win for the 100 people who can move into that apartment building.

Are you really that important?

What about the 100 people who also owned homes within a few blocks of that apartment building and are also opposed to the change that it brings to the neighborhood? Zoning laws don't exist because of one loudmouth, they exist because solid majorities of the people who live in a given area like having them.

In your example, your side is outnumbered by the residents of a single apartment building.

This whole thread is kind of silly, in that high-density apartments aren't what's going to get built on SFZ blocks in cities and inner-ring suburbs; 3-flats are.

I suppose you didn't buy the entire town, so you can't preclude your neighbors from wanting their property to appreciate, their lives to become more social, and their environment to change.

The neighbors collectively agreed to the previous zoning. Now some outside body is forcing that to change.

Once upon a time, neighbors also collectively agreed to zone by race and ethnicity, until Buchanan v. Warley in 1917 put an end to that practice and created the minimum-lot-size SFZ proxy system we have today. You can argue persuasively for respecting SFZ, but you probably can't do it from a moral high horse (which is just to say: you can't rest your argument on a moral right).

I’m not sure the implication that those of us who don’t enjoy sharing walls are immoral racists is particularly justified.

It's a historical fact. I'm not saying you're a racist. Those zoning ordinances though definitely are.

I'm speaking only to overall property values, because that's the argument I was replying to. I don't care about your preferences.

I am responding to your first sentence, which is "Upzoning is a win-win for existing homeowners", which is not true in general.

It is true in the sense that I meant it, about property values.

Nor do you apparently care about the fact that "NIMBYs worry that the mere existence of nearby multifamily will decrease their home value" is a false stereotype.

A NIMBY straight-up told you that their motivations are about lifestyle and not money and your response is "I don't care about your preferences".

I’m genuinely curious: Why not? What difference does it make to you what’s next door?

sound, privacy, views, for example.
