Let me see if I can explain my definition of intrinsic value.
Suppose a genie appeared before me and presented a gift to me, with one condition (enforced by genie magic): I can never sell this gift. The gift is a gorgeous, hand-engraved Krieghoff shotgun stocked in highly figured walnut. Now, this is a coveted object and one that would fetch a high price, if I were able to resell it. It's unfortunate that I can't! But I would still be thrilled to receive this gift. It's a very fine piece of craftsmanship and one that I can both appreciate for its beauty, and enjoy using on the skeet field. I want it just to have it and use it, not to sell it or put a number on it in measuring my assets.
You can imagine the same arrangement for many other things: a fancy car, a house, a stunning artwork, a barrel of booze, or even a pile of heroin and cocaine, if that's your preferred vice. Even with the stipulation that you absolutely cannot sell the item, you still want it.
Now, if the genie gave you a gift of Bitcoin, with this same magic arrangement that prevents you from selling it to somebody else (including trading it for anything), how excited would you be?
