Healthcare is most definitely producing goods. People will consume it much over their needs if it is free. A fire department or police are not, people will not call the fire department for the fun of it, only if there is fire.
That said, healthcare is definitely a troubling one because its interests do not align particularly well with a profit-driven model. It should probably have some kind of halfway model to discourage overt usage while ensuring people get healthcare in the scope they need it even if they have a bad financial situation. I don't have a good answer for it.
If only there was some sort of organization, beholden to the people by democratic election, which was obligated to protect and provide what does not particularly align well with a profit-driven model (military, roads and public transportation, fire & police services, sewer and water systems, GPS and weather reporting), to provide this other thing that does not align particularly well with a profit-driven model... hmm...
everywhere it's been done universally and not under/defunded for electoral reasons, the combined economy of scale/standardization, removal of $100Bn+ middleman industries and cheap proactive preventative care saving on expensive emergency treatments more than completely negate the "people going to the doctor for funsies" cost
I was speaking on behalf of the US in this instance, I do not believe the US GOV is capable of pulling a working public healthcare program for their scale.
