>National security and "public safety" carve outs need to be eliminated. So long as those exist, we have no right to privacy.

This is overly absolutist, or maybe idealistic view. National security and public safety IS more important than individual right to privacy. As an extreme example, if your friend was dying, you had a password to my email, and you knew that you can use information in my inbox to save that person i really hope you would do it.

In general I think that police with a court order should be able to invade someone's privacy (with judge discretion). I mean they can already kick down someone's doors and detain them for several days - checking email doesn't sound too bad compared to it, does it? I think they should also be legally obliged to inform that person in let's say 6 months that they did it.

The problem is that modern world is drastically different than the old world when you needed to physically hunt down letters. Now you can mass scan everyone's emails, siphon terabytes of personal data that stasi could only dream of, and invigilate everyone. This is something that is worth fighting against.
