I don’t think what you’re describing is wrong. But a belief that something is a natural monopoly causes us to make policy choices based on a flawed assumption. Flawed choices about the inevitability of a monopoly tend to entrench same.

E.g. our municipal broadband monopolies trace back to a belief that wireline phone and TV can only be monopolies. And maybe it’s true! But we might have chosen differently, had we not assumed it a natural outcome.

We might have assumed that wireless is a natural monopoly. Gladly, we didn’t. (Though spectrum policy can be more competitive.)

This is not about inevitability and immortality of monopolies, but their likelihood and the detrimental effects they bring on while they exists. Both can be pretty high in some domains, so it is worthwhile to think about it, to me.

Please elaborate on what you mean by "chosen."
