It's very frustrating to see the density that passes for "rational argument" these days. "Concourses A and B both have artwork in the same locations as my garden, and the airport is not requesting to remove those pieces. It’s unclear why Concourse C can’t be built-out similarly to Concourses A and B.”

No, it's not unclear. There are a ton of reasons, laid out throughout this article, and you responded to precisely none of them.
