Of course the whole pizza thing is just sarcasm. Pizza is governed mostly by free market economics. Pizza shop owners are subjected to market completion. They must supply a good product or risk going out of business. Police units do not have to give two shits as to whether or not they do a bad job. Most of the time when they do a bad job they only earn themselves a paid vacation. I'm just trying to explain why having monopoly funded through taxation (force) is a terrible burden on any market economy.
