>The riots would collapse society.
Except you're starting to see the first cracks of that, but we're just too busy to see it: when you have people willing to die for a chance of a better life, then you're not that far from it.
>To imply that longevity will not some day be available to all is absurd.
How can you say that when longevity isn't available to all in the current days?
>There is no renewal process. There is only a permanent end. A void that you will never escape from.
Of course there's a renewal process, old habits, vices, skewed and biased perspectives of the world are all flushed and reset with death. The only void is the space you leave and that will eventually be filled up, and that's ok.
