>I addressed him
That's the part I was replying to. When you say "I agree" with parent post that disagreed that "[monopoly] is also good for society as a whole."
>A monopoly is a farm,...
I wasn't replying to this alternative analogy. I think we both agree that PT wasn't using "monopoly" in this manner. His usage of "monopoly" was closer to your "jungle" ecosystem. My point was that you may actually not be disagreeing with PT.
What you're describing is a jungle. Niches with dominant players that share in a diverse resilient economy. Bees and hummingbirds compete for the same resources but they are not copycats.
A monopoly is a farm, an established entity that's taken control of the local system to suppress disrupters.
