> Building up vertically on a x30 multiplier doesn’t mean that city can provide all the services and access resources to service the multiplier effect of said parcel of land. You're right, all the services are more expensive per square foot of land. But, it's more efficient per person, and per square foot of property, to provide those services in a smaller area. Cities are more expensive because of simple supply and demand: a lot of people want to live there, and there's a limited amount of property.
