That's an interesting assertion, but not supported by any evidence that I can see. And OTOH, there is direct contradictory evidence suggesting that there is another viable business model for building this kind of infrastructure: non-profit member-owned cooperatives. The same kind that provide telephone, cable and electric service all over the country[1].
Note that I'm not saying that cooperatives are a panacea, but their existence is evidence that other options are available. And before somebody screams "but aren't they all subsidized by the government", I would argue that if the kind long-term stable returns that the author of TFA speaks of are really available, then there's no reason to think that a coop couldn't get a loan (or equity investment) from private institutions.
My guess is that the biggest thing preventing this kind of thing from happening more often is exactly the amount of red-tape and government regulation involved.
