There are no private parties anywhere that exercise the power of "eminent domain". Even utilities incorporated in the same manner as municipalities (e.g. just about every high energy power line in America) only exercise eminent domain through government agencies designed to take care of the details for them. In most cases the power company is after an easement and not full ownership. Farming, et al, continues to be done UNDERNEATH THE WIRES.
I doubt you could find a politician in the country who'd agree to a private agency or individual doing eminent domain!
Private RE developers using quasi-public sleight of hand through state administrative processes does not make casino/mall/housing development a “government work”.
