Why should the NHS be the exception? Because there's no choice about using it. I can change my email address. I can change my bank. I can cancel my cards. I can change my phone, both the physical thing and the number. I can have insurance against credit-card fraud both online and offline. I have insurance to help replace the things in my house should someone break in while I am on holiday. Almost everything in my house, almost everything in my life, is utterly replaceable. My body, my health, the NHS and my medical records, though... I can't just switch to a different provider or decide to stop using it. That's why the NHS is an exception.
