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).
Not in the other poster's proposal. The proposal was that the business should NOT have the benefits of the police, fire, street or sewer. If the proposal is that they should NOT receive these services, then they should not be expected to fund these services.
Unless of course we are a socialistic society. Oh wait....
