GitHub has the concept of an “account successor”, where if you die, someone you designate can take over your repositories / accounts.
I propose something similar, where you can designate a successor for your company. If you are inactive a certain amount of time, your successor gains access to your company, via a context that allows for transfer of assets, but no production or flight of ships.
This sounds like a big task, but it would enable some recovery of assets when a large debtor disappears.
