What device level do you speak of? How does one get medical records onto the device? Where does one backup the said data off the device, as is normal with all devices today.

I repeat - your argument is based on cherry picking Apple propaganda. It's like saying "emails stored on Apple devices are encrypted". Which they most certainly are, but if subject to Chinese law, even if Apple's email service were end-to-end encrypted, they'd have to provide encryption keys to the government. So all this "email is encrypted on the iPhone" is marketing fluff
