The US did do this for most of the 20th century. Or at least something close to this: Many utilities were private companies but they were regulated monopolies. The state allowed them to be monopolies in exchange for tight state control.
In the 1990s this started to change. The idea was that the different utilities could compete for customers, and thus they wouldn't be monopolies any more and thus market forces would take the place of government regulation.
Of course this has failed spectacularly. Deregulation brought us the Enron disaster and the 2021 Texas grid crisis, among others. But since corporations control the US government now, there's no chance regulation will be brought back.
