What a disingenuous rhetoric. Degrowth is centered on meeting people's needs. No one needs a house. Everyone needs a home. Not everyone needs a home in Vancouver.
One central tenet of degrowth is accepting that nearly everything, at some point, will have to stop growing. This includes Vancouver, and a reasonable person could conclude that this headline is an econonic signal that now is probably the time.
Until absolute population declines, It's a big country, medium density development in other areas can accomodate everyone more cost effectively than more unaffordable skytowers in earthquake vulnerable Vancouver.
