Okay, this comment reminds me a bit of the economist joke with the $20 bill[1].
But the essence of the comment is spot on, these apparently barren landscapes of competitors often have a cause, and so just finding such a market is only the start of analyzing WHY it seems to be so noncompetitive.
[1] Two economists are walking down the street and one sees a $20 bill on the ground and picks it up. The other asks, "Why did you pick that up? It's clearly counterfeit, if it were a real $20 bill someone else would have already picked it up."
