By Definition the government produces public goods
ranging from parks to sidewalks to national defense.
The free market sure didn’t produce I-5.
You need to produce better examples.
*Parks are public owned property, not a produced good. The maintenance of said property is a service.. though now they have individual fees on such parks which were initially provided by through general taxes.
*not all sidewalks are done by the gov. I fact, most are done by the property owner as a requirement… as well as roads in many places. This is why you will often see sidewalks, curbs and roads in the middle of new developments before the houses are completed yet.
*national defense.. is a service not a good.
*I-15 was contracted out.. it was not build by the government.. as with virtually all highway work.
