They’re not talking about natural monopolies. A natural monopoly is when there’s some barrier to entry that prevents competitors from entering the market, like a need for prohibitively expensive infrastructure.

What OP is talking about are situations like Walmart opening a store in a new location, operating it at or near a loss to drive the local competition out of business, and then jacking up prices once no competitors remain. The government isn’t forcing them to do that.

lonelygirl15? I remember a friend telling me about that series because she wanted to share a funny video reply (Remember those?) by somebody who managed to find the same animal plushies that the girl carries around; it was a parody episode where the plushies talk about the current situation in the story and suggest that maybe the girl should drop all the teen drama stuff so they can all focus on running for their lives instead.
