You have to pay for food. That doesn’t mean that eating isn’t important or that a society wants people to go hungry. By your logic, the private market would just be the domain of luxuries and useless trinkets. The government here provides health insurance for the very poor and subsidizes private insurance for the somewhat poor.
Police and fire are public services because they would not work as market systems. Fires spread from house to house, for example, regardless of who pays or doesn’t, so private fire brigades would have to protect non-payers in order to also protect payers. That’s a classic market failure that can be solved by public services. (Potentially, that problem could have been solved by requiring fire coverage, but then there's the further problem of a row of houses, each with different fire services, some better than others, with the better ones still needing to protect the houses insured by the worse ones to protect their own customers. Not to mention that
a single house fire can lead to a whole city burning down. It's just not a service that the market can effectively provide in most places.)
And no, of course people don’t completely waste care in other systems either. That’s because it’s rationed by the government. Elective procedures have long wait lists, access to specialists is specially guarded, etc. Limited resources always have to be rationed by some mechanism.
Our system in the US is far from perfect: we let the doctor’s guild limit the supply of doctors, we are too uncomfortable with ending care for the very old and terminally ill, and the whole hospital and medical device industries could use an antitrust shakeup.
