Let´s assume that your theory is correct for a second. What exactly is the argument why silver will have higher gains than Gold
in this scenario? The industrial usage?
There's numerous reasons:
1) Silver is the most downwardly manipulated commodity on earth using paper derivatives in the concentration of traders in the CFTC COT.
2) Trading the GSR is an actual thing.
3) Organizations like The Pilgrims Society which sought to suppress the market cap of silver no longer have any reason to do so. Nations like India and various Arab states have hoarded tons of gold now while the west is empty of gold, so instead of suppressing silver, these organizations have more incentive to try and suppress gold and pump silver now, otherwise the old world order becomes slaves of...India? Yea, that's not gonna happen. Entities like Russia don't really care if they try and pump silver either since Putin has been stacking silver. Putin is prepared for whatever happens.
4) The ideal form of money does not have zero intrinsic value, it has the most intrinsic value. Meaning if it was possible, humans would likely be using blocks of pure energy as money like the transformers cartoon. Since we do not have the ability to store energy like that, some sort of metastable commodity like oil that produces energy would be the next best thing, except for the fact one of the main purposes of real money is to remove counterparty risk, and you simply can't do that using oil as money, not to mention oil performs mediocre or poorly in the other traits required as well.
Since we don't have any viable way to use energy as money while satisfying the traits required of money, a standard physical matter commodity currency is the next best thing because matter is energy anyway. In the old days, to the dismay of the aristocrats, the amount of economic activity done in silver was always so high, it would constantly creep up on gold. Since the use cases of silver have vastly increased since those days, while gold has not, if an actual free market occurs, silver will likely rival or defeat gold in market cap.
5) It's likely JP Morgan rigging the paper market while buying the physical market is just a form of stealth confiscation of metals without going through the route of using an executive order, then the US govt will use this as a last resort to back it's currency after the dollar implodes since the coinage act of 1792 says $1 is supposed to be composed of 371 grains of silver anyway. Canada also has zero gold, while Mexico has lots of silver. If you live anywhere in North America, silver will likely be huge in the future, while silver has always been huge in China and India in the past until the western money powers tried to sabotage them with things like the opium wars.
