Important to note that this is still pretty true for non-urgent care. My city has three somnologists' offices. If I have a sleep issue, I may have options, but there are very few of them. It's much more plausible for someone to buy up the three somnologists than to buy up, say, all the pizza restaurants in the city, and it's harder for someone else to start up a new somnologist than to start up a new pizza restaurant.
