Yeah, at least with the way things are, and even for the fact that even if you are not going to be trusting your attorney or anyone around you to hold your private key, one can generate a paper wallet or get a cold storage to put the funds in a bank to store just the way people store gold in banks. In that way, anyone can make it accessible to their next of kin in the case where they are deceased or simply write a will to let them know there is something left for them as inheritance somehow. What a waste right now! $1 billion ?
Yes it is a waste of $1 Billion, sadly.
I disagree with you when you say you could get a paper wallet or cold storage and put it in a safety deposit box at a bank. Your funds are only secure as long as nobody has your key. If they are written on paper and stored in a box at a remote location then I do not class them as safe and secure.
Something else needs to be done, a better way to secure the keys yet making them accessible to those in your will when death occurs.
