Dead Man Switch

I was wondering about the effects of bitcoin becoming permanently inaccessible from death of holders without an inheritance plan. Isn't it estimated that somewhere around 3 to 4 million are already permanently lost?

If most non-institutional bitcoin end up lost, the rest of the bitcoin are being held by ETFs, banks and governments. Then bitcoin's core ethos of decentralization is undermined. Liquidity becomes centralized. Custodial bitcoin remains.

There is no incentive for institutions to discuss this issue. I suspect this strategic silence leads to the slow centralization of bitcoin and while most of us are just going 'price go up'.

There seem to be very few wallets with inheritance tools. Personally, I propose a 'dead man switch' protocol be implemented for wallets that have no inheritance management to recover bitcoin, although I wouldn't know how that would work. Even then it would have to be adopted by us retailers.

What are your thoughts on this?
