This is one of the reasons why some set of people will never safe their money in bitcoin wallet, and if you look at it they are correct, with the high level of hack happening I won’t blame anyone who refuse to invest in bitcoin because there money is not even safe.
Just imagine having all your life savings in a particular bitcoin wallet and you wake up one morning and realize that the wallet was hacked and all funds were stolen, you may lose hope and die out of shock because you no you can’t get your money back, but if you here such news about a Nigeria bank you will be scared but you have hope that you can at least get half of your money back if not all.
Non-custodial wallets give us full custody, we pay the price for whatever happens. In a working system, banks should be able to trace and recover stolen money from a customer's account, also with the aid of the police. In all interventions, the affected person should be able to recover their money or get hold of the perpetrator.
That is why self-custody will always be an option, no need to put all life savings in Bitcoin, all who want can diversify. I'm not scared, but I do appreciate diversification of assets into separate markets, business, etc...
