They are discussing physical immortality, haven’t made distinctions about soul immortality or spiritual immortality.
I happen to agree that death is necessary and evolutionary, and it applies to soul and spiritual imimortals as well – their death comes as they complete their process in each dimension and “die” into the next. At some point I belieev everything is recharged (unconsciously,) into the Supreme Unknown, wuji, and re-emerges. Unchanging change.
