I think this is a bunch of retrospective justification when the truth is that home-owners vote against supply expansion measures that may decreases their home value (their main investment).

Just like how people pretend "I'm actually super concerned about emergency vehicles" when it comes to replacing a car lane with a bus/bike lane. It sounds better than admitting they don't want to be inconvenienced, they'd rather have an extra car lane than someone else get a bus/bike lane, etc. So the hand waving begins.

Austin is unique even in Texas for its aggressive construction boom + decreased rent, so it's not even a Texas thing.
