If all of the sudden the neighborhood behind you gets rezoned to industrial and you get a datacenter nearby, everybody understands you're up in arms.
If at the same time the neighborhood behind you gets converted from 200 single-family homes to 200 8-plexes, complaining is NIMBY. Even though it has the same dramatic impact on the quality of life you bought into. Way more noise, way more street parking, cars racing late at night etc.
We’re not talking about a sewage treatment plant or even a data center, we’re talking about fellow members of our community living in code-compliant housing.
So absent of that, I think your personal incentives also lead you to your current housing policy preferences. Don’t you?
