We need infra for the people who are already here. New and updated infra is important to help draw more people in too. But infra alone doesn't do it. Has to be paired with decent policy. People have to see and believe that the city and state are actually addressing infra here. A bike master plan, for example, doesn't mean much if you don't have a good track record of installing, maintaining, and enforcing the bike facilities.

For the sake of completeness, crime is also an issue that creates challenges to increasing density.
