I spent 30 years thinking I was cishet (and suffering for it). When I finally realized that I’m trans, it was like a dam bursting; suddenly everything about my identity was in question. I’ve gone from “Maybe I’m a girl” to “I’m a trans demi ND plural therian” in three years and I don’t think I’m done discovering things about myself yet.
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.
