You're right to a large extent. This king-of-the-hill attitude towards property is exactly what you see with Prop 13, rent control, severe building code restrictions, etc.
Prop 13: The long-time home owners get to put a disproportionate amount of the tax burden on newer buyers.
Rent control: long-term renters put a disproportionate cost of the rental prices on newer renters, and landlords.
Building code: Land owners want to be able to build when it's their turn, but as soon as they build they want to restrict others for obstructing their view, or changing the character of the neighborhood.
Public transportation: Residents who don't use public transport have typically fought against it coming to their neighborhood to keep the undesirables out, then find out that their property values are lower, or shops aren't doing well, because of this 30 years later. See Georgetown, DC.
Basically, everyone wants to lock in their position, then keep everyone else out. That's really only rational, so I can't fault it that much. Where I personally get annoyed is when those motivations aren't acknowledged and also get paired with complaints about super high rent and property prices.
The "rush to grow" is simply the reasonable response to skyrocketing prices. If the city doesn't want to grow, then it should be ok with those prices. What's not reasonable to want to be a desirable place to live, not grow, and have stable, affordable prices.
