[ExI] any exact copy of you is you + universe is infinite = you are guaranteed immortality

Yes, that's true, but it's true whether or not a particular
you dies.

Yes, true, though again you seem to be inferring a
causality between "you die" and copies trillions of
light years away being "brought to life". In reality,
you are a set of patterns, and you get run time
wherever something sufficiently similar to you gets
run time.

I think that your measuring rod is incorrect. You seem
to be asserting that since the number of copies of you
is infinite, then plus or minus one more doesn't make
any difference.  But there *is* a difference!  If you
die *here* then you also must die in a certain fraction
of similar situations, also infinite in number. So we 
must abandon numerical or cardinal identity and 
speak of measure instead. 

(I assume that you understand that if you die "here"
then since similar circumstances occur everywhere
---within a large enough radius of spacetime---
then the same circumstances obtain in a definite
*fraction* of spacetime.)

It is absurd not to worry about a loved one. If the
fraction of solar systems similar enough to this one
to contain a copy of your loved one, then you
should lament their passing. And of course, this
will include yourself, normally.

No, for the reason given. For you to die in a fraction
of universes cuts down your total runtime by that same

Yes, but only if you realize that you are already living
in your copies whether or not your local instance
