You're welcome. Part of that conclusion is the premise of reality that has the counterpart of death. Therefore, if there is no death then there is no life really. Life requires death. If it was otherwise, it wouldn't be called life. Biological things have life because there is death. Removing the finality of death would mean it would be called not life, but something else.
Endless living means you lose sight of the finality of life, and the need to do something meaningful with the short time you have. You can just push it of, and wait until you feel like it. You care less about doing this. Higher meaning and purpose get devalued. Ease, comfort and sensory gratification become the norm for quelling the long repetition of days going by on and one. Pleasure for self takes over moral concern that includes others.
Talking to my wife about these things last night it struck me that it is an economic concept as well. The same way that scarcity/rarity translates roughly into value for gold.
