I had a similar issue with refusing to give a podiatrist I saw one time my SSN. The rationale was, prior to getting a surgery once, I was asked in pre-op to review my EMR information by the nurse. The info was completely wrong and very dated. I asked the nurse where the info was from since I had never been to that hospital chain before. Her comment was an affiliated urgent care I went to years ago was in their medical system. But the brand name was different because they were acquired. I was pissed. What if I had been rolled in unconscious and that EMR record was meaningfully inaccurate against my wellbeing? So now it raises eyebrows but I refuse to provide any nonlegally required info. And to OPs point the response is one of almost mocking surprise. But the counter argument is, why would I trust you to not sell my data going forward? What if I'm wheeled into a hospital unconscious and your medical records from 20 years ago somehow cause me harm? Absolutely no way.
