I think this is Jacques' approach. It is an absolutist point of view which
assumes an external observer looking at the death of a person and observing
the "trimming" of his branches.
The following is the relativistic approach which requires a first person
perspective: what would the person who "dies" sees along the "few" branches
where he is still alive. Does he see a decrease in his own measure (as the
independent observer sees) or does the universe appear to him to be more or
less always the same? My contention is that branches are infinitally
divisible, and no matter how many times he has died, there will still be an
infinity of branches still available to him. FROM THE SURVIVOR'S PERSPECTIVE,
the world appears the same. If he had an instrument to measure "measure" he
would not detect any difference. In fact the infinity in the number of
branches makes the design of such an instrument, a physical impossibility.
BTW, in Astronomy, the constancy of the universe with position and
orientation is called the Cosmological Principle. I am proposing to extend
this principle to the MW.
We have all in fact died many times already, except that we are not aware of
it. So, dying a few more times should not change things much anyways.
