This is something I advocate/educate on in my professional work. Being able to explain to a judge the nature of private keys, cryptography, and irretrievability has literally kept clients out of prison. We don't have debtors' prisons in the US anymore, but if a bankruptcy judge, for example, does not believe you when you say you lost your private keys, you will be sent to prison for contempt until you produce the money--which of course you may not be able to do even if threatened with contempt prison.
