> Infrastructure costs increase as you increase density.

They increase much slower than the efficiency gains from having a higher density and the rate of per capita costs decrease from having much more people pay for those costs.

When a city passes ~20,000 people per square mile the per person cost of infrastructure increases as roads stop being efficient. You start needing tunnels for roads and or subway systems. You also need deeper pipes for water etc, it’s not a deal breaker, but it is a real issue.

Having existing residents subsidize new residents is a common approach, but understandably unpopular.

Where does this 20,000 number come from?
