The more people use those services, the more frequent the service can be made, which leads to a better service. The opposite applies as well. Take the example of low-density housing. I remember being in by-elections in areas not far from Dublin, where houses were being built, one or five to the acre, and then demands were being made for a very good bus service, but there was very few people in the area. I could understand their frustration, but the reason there is a very good service in London or Paris is because the density is so high.
