there is no consumer choice in a natural monopoly. that's why it's called natural monopoly.
I don't think that contradicts what the person you were replying to said. Specifically, they said break it up or make it public. If there is no option to break it up, then making it public is the only option.
Well, wouldn't it have to become a public good / public utility then? Isn't that what we're all talking about ITT?
