I didn’t miss anything. You can substitute in any real or imaginary rare and expensive disease if you want to define “healthcare” as something that excludes the general ability to see doctors and receive treatment for common illnesses and injuries.

If you’re dead set on arguing about an arbitrary imaginary definition of a word, the world is your oyster. You can say sickle cell or Methuselah Syndrome or Tandy’s Malady, it’s all gravy if you can convince your mark that whatever you’re talking about is the same thing as the broad concept of healthcare.
