Thats because roads are not "supply" it is "price". Building a hospital and staffing it should make the cost of healthcare in an area lower because there is more "supply" of healthcare. Which in turn means more people would go get healthcare that couldnt afford it before. The sick people are already there, they just cant afford to get treatment. Just like the people who want to drive somewhere are already there, but the cost of a clogged commute makes it not worth it for them to spend the time, so they do something else.
