You started out in this discussion with the absolute that under no circumstances should patient confidentiality be breached. I see you're not quite so adamant for the absolute as we've realised that there are circumstances, enshrined in law, that allow breaches. You seem to be saying in a convoluted way that even though there are exceptions to privacy laws, no more exceptions should be enshrined in law, despite that mankind's advancing knowledge of things such as genetics does make some laws, or parts of them, redundant or obsolete.
