Yes, clearly that could happen in the future. I thought we can synthesize it today, except the cost is much more astronomical thus not economically feasible. But you are also stating that you will spend $$$ on technology to have a lower ROI over a larger dispersed area (though no human labor). Even space exploration. How much does that cost? Are you willing to provide free excavation, logistics, processing and manufacturing in order to eliminate the cost of silver itself in order to provide no cost silver especially to people that give it value? Or is all that higher cost time/labor/space exploration suitable when only trace elements are available on Earth, which would probably mean that PM prices are much higher if supply is severely restrained to support the higher cost of such an endeavor. That is assuming there is any demand, if there wasn't any demand why go through all the effort to create/space explore for PMs ? Unless it's for sport, which would give the PMs some type of value.
As water pollution and global warming intensifies, more effort will have to be made in distilling sea water into fresh water for survival. An effort could be made to intensify techniques to extract the 20 million tons of gold that is diluted in nano size in the total oceans. The Salton Sea, in southern California desert was formed from Colorado river water in 1908 this time ( it has formed and evaporated several times in last 1000 years by nature). It is slowly evaporating more during the last decade than before due to water restrictions in farming. The residue should be more concentrated in all minerals.
All of the gold on earth or the solar system for that matter comes from stellar event beyond it. The thought use to be maybe it was formed in stars, but the nuclear sequence didn't fit, here is how -->https://www.cfa.harvard.edu/news/2013-19
It,s very likely that gold is being delivered to the Earth in both small and large amounts on a regular basis thru astroid or comet hits. Some of those rogue objects may even contain large deposits of many precious metals. All the mass of the solar system is the product of super nova events, including all life. Both us and the coins we collect are all made of star dust from a super nova explosion about 5 billion years ago. All that said, there,s still not enough of the valuable metals, precious stones, etc. to back a monetary system with 6 billion people. Most of us never really see much of the stuff, so a balance of productivity and credit is what makes the economy function. The precious metal and gems are only emergency funds if and when needed.
He's actually pretty much spot on. With the amount of wealth in the world it's impossible for a precious metal currency system.
I dont take drugs especially prescrption drugs. You keep them, youll need them for the upcoming world events.
It comes down to what circumstances led to the downfall of "worthless" precious metals. In an event of a war - most certainly. You can't feed yourself an ounce of precious metal. Heck even a bottle of water would be more useful.
The problem is; what is that bottle of water worth? Would someone sell water or food ? Or would they simply kill for it? Are bullets then worth more than PMs ? but how do you buy those bullets? Just with food? When did Commerce start? Trading one food product for another? Or one non-food product for another? If one does a study in worn-torn areas of the world, looking at past history one might get a better understanding of this. You'll also come across black markets and their impact.
The ability to make synthetic diamonds didn't affect the price of real diamonds. Maybe because they are detectable but presumably the price of manufacturing products that use diamond must have bottomed out though.
Neither has the ability to make silicon-carbide ("moissanite") gems with ever more fire than the best diamonds, natural or synthetic. Supporting the price of "real diamonds" has taken a great deal of effort on the part of a pre-existing worldwide cartel. I'm not sure that's the best comparison, but hey, if we're talking about a science-fiction scenario, I guess anything goes.
I'd dare say that synthetics may make natural ones even more rare/valuable as the synthetics and faux (CZ's) become more prevalent in the market.
