we need our dollars to be made by governments, not basement dwellers.
Most governments are very young, and do not last very long historically. Central banking is a handful of decades old, cryptocurrency is one decade old.
Neither the maximalists nor deniers are right at this point. It remains to be seen when/whether cryptocurrency will replace fiat currency.
Also, gold is not inherently valuable. It will become a regular common metal once we shift extraction to the asteroid belt.
The truth is there really isn't much with "inherent" value out there, with the notable exception of potential energy.
There's always another train, right up until the point where everybody assumes that there'll always be another train and world domination is assured. At that point, it's time to hop on another track.
