Can you describe a monopoly that isn't "natural"? I see what you mean but struggle to think of a traditional monopolistic company that doesn't have a "we started with the industry" defense.
The ISP in your area could be an unnatural monopoly. In my experience these companies have lobbied out local providers and bought all the competition to make them the only offerers in some areas. It happens more in rural US. The issue also crops up with gas stations in towns and then again with dollar stores as well, in this case they are replacing grocery stores.
Traditionally the federal government would crack down on unnatural monopolies so that's why you don't typically see them, but look at the regional level and you can spot them.
Balance of probability, maybe rephrase as "anti-consumer behavior is bad" or "noticing how monopolies are inherently self serving is a lot like a frog noticing the water around it is getting a bit hot"
