Indeed It's far more necessary that the utter dregs of humanity (e.g. Peter Thiel) eventually die of old age. Or put another way the damage of mortality killing good people is more than offset by the good of it killing the worst people with the most power. Because in the end it's probably not going to be your sweet mother who will get to live forever, it'll be people like Peter Thiel. No thanks, for the good of our species.
“Those who used the Nine Rings became mighty in their day, kings, sorcerers, and warriors of old. They obtained glory and great wealth, yet it turned to their downfall. They had, as it seemed, unending life, yet life became unendurable to them. They could walk, if they would, unseen by all eyes in this world beneath the sun, and they could see things in worlds invisible to mortal men; but too often they beheld only the phantoms and delusions of Sauron. And one by one, sooner or later, according to their native strength and to the good or evil of their wills in the beginning, they fell under the thraldom of the ring that they bore and of the domination of the One which was Sauron's. And they became forever invisible save to him that wore the Ruling Ring, and they entered into the realm of shadows. The Nazgûl were they, the Ringwraiths, the Úlairi, the Enemy's most terrible servants; darkness went with them, and they cried with the voices of death.” - from the Silmarillion but it’s echoed in LotR also. And even Bilbo complains of being “butter spread over too much bread”.
