What's the point? If the encryption is weak enough to be broken by the average owner it's weak enough to be broken by anyone.

I think this is primarily a UX issue, encryption should be strong but users should be "forced" to create backups of their keys, with options to store the full key in a safe place themselves, or to distribute parts of their key to trusted people using Shamir's secret sharing.

In other words don't weaken encryption, allow users to weaken their key storage after informing them about the trade-offs, if they so desire.
