It should be mandatory to give (at least) three addresses upon wallet creation. Either from relatives or with a random option of a list/pool that maybe gets updated or selected at random, and triggered via dead man's switch.
I don't know if you ever wondered what would happen to all your email addresses and online accounts if you die without leaving your backup passwords to your family members or lawyer.
It's similar thing with Bitcoin and private keys or seed words, and I don't think we need to have bitcoin-babysitters for that.
Even if you had bunch of gold plates hidden in undisclosed secret location and you never tell anyone about that, it is lost for your family forever when you die.
Why lose coins when you could recycle them? It's all code anyway, isn't that the whole purpose of automation and self-governance?
It's your own responsibility and there is no automation in Bitcoin.
If you want to leave hidden treasure to your family you live them map with instructions how to find it, same thing applies for bitcoin.
