Yeah there's a cost. The cost is on the consumer who's being sold bullet proof vests to goto the supermarket because there's fear being created about random shootings that could happen and than you need these high tech security things to keep you safe.

This type of security e-wang crap is only suitable for highly sensitive confidential data (secret / top secret level stuff) and most consumers get little benefit from it.

Why? Because you've already handed over your data to a lot of places knowingly and unknowingly who are more likely to leak it than you ever will.
