What you describe is not "easier said than done" - automated email archiving is easily done.

What you describe is "I want less company security, more personal convenience". (As almost everyone wants, almost all the time).

It's not easier said than done because it's technically difficult, it's easier said than done because you have to shove it down users throats and they're not going to be happy about it. And because there's an associated cost to productivity.

Worth it to avoid something like Sony's indecent? Probably. Easy to convince the non-technical decisionmakers of that? I'd bet not.
