Who owns the utility?
In Canada, for example, it's common for the utility companies responsible for electricity transmission and/or distribution to be owned by provincial or municipal governments.
At least in Canada, even when a "private" company is involved, there can be significant government ownership. Hydro One in Ontario is publicly-traded, yet the Ontario Government holds nearly a majority of the shares, for example.
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.
