We don'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't waste our time doing that here). So your whole argument about all people that have ever lived is basically a strawman.
