I propose that even if the government (indirectly) owns the utility pole, using them for espionage by a different government agency is still an infringement of rights.

The government also owns schools, libraries, and hospitals, yet (I would hope) we don't want that to mean the police can get your school transcripts, library or medical records, or compel hospital staff to restrain you until the police arrive, without a warrant.

In sum, the government owns far too much to be allowed to use all they own for whatever purpose they please.
