If that's true, I think it's kind of fascinating. I'd certainly like to know that there is someone who is taking enough interest in me as a patient that they consider themselves ultimately accountable for providing or coordinating a professional standard of care. But I don't need that person to be the personal face of that care all the time, and frankly, it's ridiculous to assert the system behaves that way now. And I definitely want to know that person is operating without cognitive impairments, and definitely don't think "continuity" means "one person."
I'm sure there's realities of actually doing the work that I don't understand, and I also know that handing off information and coordinating people is far from trivial (I know that we're really not all that good at it in software, a profession where for anything to work at all you have to pass around carefully encoded instructions). I just don't understand the given argument.
Also, I see at least one professional counterargument in the article.
