>It is easy to hand wave "more building supply", but that's a medium to long term solution.

YES! It's the long term solution which if it were implemented in a timely manner in the past, would have saved us today, but even though we are in a mess today, it's not being implemented even to this day due to bureaucracy, NIMBYism and various political issues which beat around the bush, instead of saying it straight: "Build more today so we can live easier tomorrow!"

>What do we do in the short term?

Also, build more. If you don't build in the short term, there will be no long term.
