Wow, another fantastically researched article that thinks building more houses will solve the problem. Thank goodness houses take up no space, are central to where people want to be, won't cause traffic issues and scale with the population!
Vancouver really isn't that big. It's also really well-connected by transit. Currently, only downtown is dense (and some small pockets around SkyTrain stations), though that's been slowly improving with new developments.

This seems to be a very pedantic argument where you are using the word housing to mean exclusively single family housing were are the author of the article is pretty clearly using the term to mean all forms of housing including condos and apartments.
Sorry if I’m confused, but are you suggesting housing doesn’t scale with population and traffic? Without new housing prices and traffic will only get worse with people sprawling further out for fewer units.
