Don't know if you've read his paper on Bitcoin, it's a decent one, it roughly boils down to two points: 1) no benefit in the meantime for the holder (such as a dividend or direct utility from the thing itself - a painting can be hung on a wall to look nice), 2) non-zero probability of perishing over any time period. From those two premises one can indeed conclude that the asset should be valued at no more than 0.
On the surface this is right, however I'm wondering if the first assumption is actually true. People do get some sense of fulfillment from participating in this "revolution", sticking it to the "big system", protection of capital from the "insane inflation", or just plain bragging rights (ex: laser eyes). Should this type of a benefit exist indefinitely then the conclusion of it being worth <= 0 isn't correct.
