I intentionally left out YIMBY moral grandstanding, because it's usually a shield to hide the real reason they feel zoning should be changed: "I can't afford your neighborhood and I want to live there"
There's no moral grandstanding. Some people just think you shouldn't be able to be so rich. The reason you are is because the masses allow you the privilege. You might as well be graceful about it.
At least be straightforward with the reasoning, then. If the mainstream YIMBY said "I want to live in your neighborhood and I can't afford it, therefore the zoning should be changed", or "you're too rich because of zoning so I want to remove it so we are more equal," I'd have more respect.
But usually it's something about how mixed use neighborhoods are better, or how someone on minimum wage can't afford to live on their own in a very expensive neighborhood. Ok, but those probably aren't the real reasons you're advocating for change. Just be direct.
Language that straightforward is surprisingly hard to find among the YIMBY croud.
We live in a highly competitive individualistic society where money and power buy all, including the ability to dip into playing zoning games using migration strategies. If people don't like that, they should move to a region which has a society more in accordance with their values.
