Similarly IMHO is listening to Bach or Beethoven a better experience when performed on "authentic" instruments and in rooms the "right" size? I don't think they're mutually exclusive. As to food, I've enjoyed "interpretations" of pizza in quite a few different places, including Napoli. Is the classic pizza margherita my favorite pizza? Not necessarily.

I'll still agree with the OP to the extent that in at least some parts of the U.S. (and Canada), fortunately including our neighborhood, there's an incredible variety of national cuisines to enjoy and to whet our appetite for more travel to compare their version to "the original."
