Having a profit motive drives a behavior of raising prices as high as the market will bear. That inherently excludes citizens who cannot afford to pay the “most efficient” price, who are often the ones who need the service the most (e.g. busses and other public transport). That reduces the ability for society to operate as a whole. If someone can’t afford to get to school, or to an entry-level job, how will they ever be able to move up in skills and pay? Who will the high-end electronic store sell their products to if people can’t afford them?

Municipal services are meant to serve as many citizens as possible, not to extract as much profit as possible, because it’s an overall benefit to everyone.
