I don't know if I have discussed "intrinsic" demand with you specifically but I have pointed out many times that there is no such thing as "intrinsic value".
Of course there is such thing as intrinsic value.
You are confusing utility with economic value. Something doesn't need to have a utility for a demand to exist. Used stamps have no utility but some types have a very high price just because of their rarity. Misprinted stamps should have even less utility but can be even pricier.
Sure. Add Pogs, Beanie Babies, tulips and thousands of other things to the list too. Demand can be driven by other things than intrinsic value, but that doesn't mean intrinsic value doesn't exist.
Even something that is essential for survival (and therefore, has an automatic built in demand) may not have any speculative value because of the supply side of the equation. That is why water is usually priced in cents/kiloliter and air comes free of charge.
Right. Intrinsic value doesn't necessarily translate to speculative value. Things with great intrinsic value, things that are necessary to survival, may still be inexpensive and easily obtained. At least we hope so, right?
As an example, a farmer might not be able to make a living producing food even though it has a high intrinsic value, if the supply of food is too great for him to be able to sell for more than his production costs. At the same time, another person who produces various forms of crushed rock, the type of stuff people decorate their flower beds and driveways with, might prosper economically even though their product is purely decorative with very little intrinsic value.
But introduce some sort of upheaval to the economy, it could be war, disaster, political instability of some sort, and things change rapidly. People lose interest in the purely decorative and devote their limited resources to getting the necessary. Suddenly the one producing decorative rock can't find enough buyers to make a living but the farmer prospers because the demand for food soars.
The fact remains that bitcoin has been around for 12 years and shows no signs of going away. This is in spite of the almost daily predictions that it will fail "any moment now" during those 12 years. You might argue that people are stupid to waste so much money and energy in it but it doesn't change the reality.
Blah, blah, blah. This is your mantra, but here and now is relevant in discussing intrinsic value.
