Regulation is usually what you accept in exchange for a monopoly. I would argue a granted monopoly without any regulation is evidence of regulatory capture.
If you want to argue from first principles, and we accept for a moment that granted monopoly is the system we are working in (whether or not you feel it's the optimal regime) then I'd argue there's a clear gap in regulation, as flagrant abuse of the consumer has not been prevented.
