I think with instrinsic value it is meant that you can use the "money" for itself even if nobody will trade you for it.
For example, wheat has been used as money in ancient times. If nodobdy would trade your wheat you could always eat it yourself. ...
I disagree.
When market value plummets and only the intrinsic value is left, i'd rather have a milion paper slips then a milion bitcoins.
For one, you can isolate your house with paper slips. You can also burn them for heat.
Or you can wipe your a$$ for a couple of months, although not sure if they're that comfortable.
Anyways, I completely agree with Mageant definition of intrinsic value.
The interesting thing is that the intrinsic value is usually waaaay lower than the face value, therefore does it really matter? In case of a complete crash you could wipe your a$$ with your stash of $100 bills but compared with what they could have bought before the crash. Is it any comfort in having that "option"?
Same thing with Bitcoins ... they have 0 value if no more electricity or system crashed but even if I could get something out of them it, the intrinsic value would be insignificant compared to face value.
Intrinsic value? Meh, whatever ...
