As for "I'd rather have the option to trust a handful of users which have all report that I'm dead before taking any actions" is a fair point regarding that Facebook requires a death certificate. Though, this is not the same as the Inactivity manager, which is what Google is offering. The purpose is to be a way to allow people to access content on your accounts after a period of time. It allows a set number of contacts to access your account in a provisioned way, through a very refined selection set that even breaks down separate google play stores (books, music, play, and movies.) I also saw selections for Mail, Photos, and 42 other different data points that can be sent to separate users.
It is a preemptive step by the account owner to verify their information will be easily retrieved by a family member or friend.
I would suggest taking a look at the Inactivity manager. It has a more robust set of features than most inactivity systems, and doesn't just apply to death. Even in death, it allows a family to collect photos, contact lists, and other mementos of a persons life.
On the other hand, being kidnapped for ransom or being kidnapped by the state (i.e., arrested) is a far more serious false positive, I would think, because deleting your digital data would probably make recovering a whole lot harder.
