If the person knew that there was a high possibility that he might die, then he probably should not be escrowing or giving loans.
If he told people that he trusts (e.g. family) what he was doing with Bitcoin and how they can access his Bitcoin after he dies, family members or friends could continue his business or at least close out any deals so that others do not lose their money.
Otherwise, the coins are lost.
You can't predict how much your possibility to die.
Well like you said, the best thing this, for all members is try to educate your family to understand bitcoin, and what is your activity in this forum/community, because when you die, you can give your bitcoin for who need it.
