The fact that your privacy isn't secured doesn't automatically mean that it is automatically compromised, does it? I mean, sure, maybe you assume it is for any real purpose, but that doesn't mean your privacy is actually compromised.
For example, my first iPhone, I didn't have a password (I think -- maybe that was my first ipad). It was insecure, but I'm reasonably sure that everything on there was private (in that more physical sense; I have no idea about internal security of those first generations of iphone/ipad).
A weaker claim that is probably true might be: you cannot guarantee your privacy without security. That you cannot have privacy seems like too strong of a claim?
I think it's bit of a nitpick, but the iPad was under physical security.
I do agree with you though. Privacy is having your information to yourself. You don't need security for that, just that everyone else keep their nose to them self. But if you want to guarantee your privacy, you need some form of security.
