I live in Seattle.
I am all for the rebuild and densification of my city.
The city can't sprawl, and sprawl is wasteful and ugly.
Seattle was a company-town shithole for most of it's history, and only relatively recently has the nasty streetcrime and the worst of the corruption been mostly eliminated. (Most of the last bits of the bad poltical corruption left when a number of the the 40 year career party apparatchiks were invited to move to DC by their national party) The city is now ok-ish decently-ish well managed and has a thriving multi-centered economy, and so people want to live here. And I welcome them. As long as they are not from California and bring California's social and government pathologies with them.
99% of the people complaining about people moving here, are either people who moved here themselves, or are the children of people who moved here. You don't get to move someplace, and then start bitching that people should stop moving here after you move here yourself.
And I look at the buildings that are being demolished, and they made of old dried wood, and brick held together by crumbling mortar. A major earthquake, and they where going to fall down and catch fire. We need to demolish more of them faster, and build more denser buildings that are better able to resist the constant damp and moss, save water and sunlight and energy, made from steel not wood and sand.
