I've argued it before and I'll say it again. No items have intrinsic value. Concepts have intrinsic value.
The concept of a liquid medium of exchange, aka money/currency, has intrinsic value to humans. It is a necessary part of the human experience. These intrinsic concepts (there are many others) create voids that need to be filled. They create a set of attributes which have utility value (money needs to be fungible, divisible, non-corrosive, scarce, etc).
How an item fulfills these qualities gives said item it's utility, aka value. Gold, paper money, bitcoin, all have value because they combine certain attributes that make them useful as a medium of exchange. That is their utility. There is nothing intrinsically valuable about it. What is intrinsically valuable is that concept of a medium of exchange.
That intrinsic concept creates a void. And how items fill that void gives them their utility value. They are only as valuable as they are useful. When something comes along and fills the intrinsic void better they lose value.
But you're not addressing the core definition of the term "intrinsic value", which refers to its utility in itself as something OTHER than a medium of exchange. Gold use very useful for making jewelry, coating wires, and dozens of other applications in various industries. THESE are the things that give it its intrinsic value, and they are the only things. Being an effective medium of exchange does not give something intrinsic value.
No, you're not addressing the core definition of the term "intrinsic value" You are conflating it with totally different concepts. Intrinsic value DOES NOT refer to its utility, utility value does. That is the whole point of the word utility! They are wholly different concepts that you are confusing as one.
You're right, being a medium of exchange does not give something intrinsic value, and I never said it did. I said the concept of a medium of exchange itself is what is intrinsically valuable. Only the concept. How well something fulfills that concept gives it utility. And believe it or not, certain attributes are useful when seeking to use as a medium of exchange (it has to be fungible, divisible, non-corrosive, scarce, etc). That's why cows make a shitty medium of exchange, because they don't have the attributes that fulfill that need. Cows have value for other reasons. Because they have utility of fulfilling other intrinsic needs.
All those aspects of gold you just described do give it value. But not intrinsic value. There is nothing intrinsically valuable about jewelry. Just as there is nothing intrinsically valuable about a facebook like. What these things do is fulfill an intrinsic need(s).
The concept of "status" is intrinsically valuable to humans because we are "pack" animals. As is something like "love". These are concepts that are inherent in human nature.
This is why jewelry is valuable, because it fulfills intrinsic needs in human nature. It fills that intrinsic void. Jewelry is a way in which we show off our status in society. That is the utility of jewelry. Gold then, is valuable because it has many of the properties that we value in jewelry (shiny, malleable, scarce, etc). There is nothing intrinsically valuable about gold itself, just those traits. If something comes along and fills the attributes of jewelry better than gold, gold loses its value. Or worse, if something comes along and fulfills the need of showing off our status better than jewelry does, suddenly jewelry itself loses some of its value, which in turn also hurts gold.
The point being, none of these objects are intrinsically valuable, they are only useful at filling intrinsic needs. Their value comes from their utility, which is 100000% not the same as those items being intrinsically valuable themselves. Items, by nature, can never be intrinsically valuable, only the underlying concepts.
Consider meat. Meat is valuable because it has utility. Meat itself is not intrinsically valuable. What is intrinsically valuable is the concept of energy. We require energy to survive. Food is how we get that energy, and meat is a useful source of food. If however, we found a new source of food that was better than meat, we'd consume more of that and meat would lose some of its value. The further away you go from the original concept, the easier it is to see...
Take meat and break it down further. Beef, pork, chicken, etc. We value each of these differently based on how well they fill the void. What do we value, protein content, taste, scarcity (which effects price and availability), etc. So each of these types of meat has a different utility to each of us. If Beef suddenly became incredibly scarce, it's value would go up. If we discovered a meat that tasted like Pork, only much better, the value of pork would go down. etc.
Now, back it up. Food is only valuable because it fills certain intrinsic needs (the need for energy, the need for pleasure, etc. These are intrinsic to human nature). If something came along and filled one or all of those intrinsic needs better (say for instance, we figured out a way to convert sun directly into human energy), food would suddenly lose some of its value. It would have less utility.
Or what if we figured out a way to simulate taste in our brain without having to actually eat. Oh how food would lose some of its value (especially junk food that is bad for you but tastes good).
In the end, objects are only as valuable as they are useful. Gold is useful for lots of things because it has qualities that fill the needs of lots of different intrinsic concepts. That doesn't mean gold itself is intrinsically valuable. When something comes along and does it better than gold, gold loses a little value. Same with anything.
