Because there's no indication that we have access to resources to allow the billions of people on the planet to live the life of an (inflation-adjusted) trillionaire. Our exponential-growth model of resource availability and the economy as a whole is limited by basic physics to be a brief window, followed by an unknown duration of quartic growth (at best), finally approaching an asymptote of quadratically-increasing access to resources.
