Gibb Sahib, you really should think before you write such nonsense!

"The more diluted you make it, the stronger it gets. The more further away you get from the actual thing, the closer you get to the real deal.

Keep spinning the nonsense around and maybe, if you squint, it will appear to make sense"

What is Americana if it is not what you have described above?

Is Appalachian music the real deal? Yes! Would it still be the real deal if those mountain people had retained their British accents for singing , while all around them the general populace had adopted American accents?

My God Gibb, I don't think you know anything about how music develops!

Let's take another example!

Django Reinhardt. Now would you be happier if Django had played jazz with an American accent? Because he didn't! Indeed, he couldn't!
Because he was a great artist, and he played jazz with a distinct gypsy/European accent.

No, great artists speak with their own voice! They do not mimic others!
