Death and Radical Self-Autonomy

There is a helpful article about death over here at First Things.

Does radical self-autonomy extend even to death?

If death is purely subjective,
1) Those in power get to decide who is and who is not important. (Hitler can arbitrarily decide the Jews are non-humans.)
2) A man with a life insurance policy could self-identify as dead so he, his wife, or his family could cash his life insurance check.
