How do you know that it has a better track record of "stability" and "growth" than any other system at a large scale? Much of America's growth in the late 19th happened without any central banks in 1913. Most of "depressions" happened prior to that -- and there were 4 such major ones in the 19th century and many of them were directly caused by the govt policy changes -- were nowhere as severe as the Great Depression occurred after the creation of the central banking in the US.
