I would say the purposeless capture of information is the correct counter argument here.

Specifically, even if a county hired all those officers and did what you suggest if there is no purpose other than recording all this information. I believe it would be a constitutional violation. A person has the right to reasonable privacy outside of their home. License plates can and should be recorded when there is a relevant purpose to it. Such as toll collection, or a scoped traffic watch done by a police officer or a traffic camera. The dragnet collection of data for "maybe its useful" or "we don't know when it will be useful, but it might" has generally been struck down when brought to the supreme court.

For Flock's case, they don't operate as far as I know as ticket issuing traffic cameras which have a much tighter level of control of how they operate. IE: Traffic cameras have clear signs near them notifying the drivers of their usage, in some states the issuing of the citation cannot be considered criminal (Civil issuance) and must not capture faces of drivers.
