Of course the general government, the Leviathan, the Hobbesian state will confiscate our specie - gold and silver. Modern man does not like to live within limitations. The constructs of modern man, particularly the abstract corporation with a monopoly on coercion and with the ability to define the limits of its own power (does not like limits) known as the Hobbesian state will not tolerate the natural limitations imposed by the created order, one set of those natural limitations being gold and silver, i.e. there is a finite amount of gold and silver so no more real wealth can be expressed as money than there is gold and silver available. That puts too much limitation on the elites and cadres who want to fund three things: their wars and their welfare state as a means to their own overwhelming wealth and power.
When you possess gold and silver. You possess power; and they Hobbesian state will not allow you to possess power, for it must by definition have a monopoly on coercion and within that monopoly is power.
Were I to possess gold or silver, I would not possess it as an investment. I would posses it to survive when I had nothing else to offer to keep my family alive. The Hobbesian state does not what me to posses that means. If one of the corporate members of the Hobbesian state wants a world-wide monopoly on seed so that they control the very means of producing and taking in nutrition, do you not think that this same Hobbesian state would be obsessed with taking all other means of survival and denying them to you, including gold and silver? Do not underestimate the Beast.
