...why though? Firstly it's not the executive's money to actually hold onto. Secondly they have sooooooo many options where their own incompetence/mistakes will not be a factor in their money literally disappearing into nothingness. There's a reason why bank deposit insurance exists. If you think you can hold onto the money cheaply, by all means start this business and get them as a client. But you'll probably want insurance, you'll likely need some security measures, etc etc. Things start costing money. Not to mention the coordination costs for them of "yet another holder of assets". What if they want to sell a chunk of it? They need to get 60% of execs in a room every time? These people hold money for a living. I understand that they might not be aware of the latest and greatest technical stuff... but this is their job and they've likely thought of a lot of details here. There's also value in a human being the last step in the security mechanism. No matter what happens, a court order/explanation of force majeure/etc means that the money is never really truly lost.
