Like cats chasing tails, all that is urgent in contemporary discussions of the city circles around the topic of density. While this makes it easy to define the shape of the boxing ring, it doesn’t set the rules of the fight, and boy oh boy is density ever a fight. Here in Sydney urban planning discourse feels like a nightmare dreamed in a fever, a chase scene in which it is impossible not to run in circles, slowly. As someone who cares deeply about Sydney’s future, it was a sweet relief to leave Smug City for a few weeks to see how they make cities in Europe.
