We don&#x27;t have to, these (108-7) billions of people will (sadly) never ever come back.
We have just 7.3 bln people and a planet with more than enough resources to sustain them and then some more (I could give some practical computations regarding the limits to growth, but I won&#x27;t waste our time doing that here).
So your whole argument about all people that have ever lived is basically a strawman.
