"Well, then these same private property businesses shouldn't expect public benefit of police, fire, street, or sewer."
I could buy into that. So long as they became exempt from paying taxes. Kinda circular logic, huh.
Not really. If you make police to be paid by only by a certain group of citizens, you make service offered by police a club good rather than a public good. Public goods can be enjoyed by all members of the economy (by definition).
