They're two sides of the same coin. Can't have privacy without security and can't have security without privacy. Looking at the post though he's specifically talking about advanced security as a means of preserving privacy, security you'd need if (based on his model) targeted by a government (whether foreign or your local police forensics team). I don't think his model is correct though because while extra hardened security is useful to protect privacy in such an instance, it's also just best practice because it's better to have too much security than not enough, just to keep your bank account secure at least.
