I don't think you do.
What in particular do you think I'm wrong about?
Ok to begin
You have stated that all items can have Intrinsic value based on the value we assign to them. Thus crypto, having been assigned a value by the market means it has Intrinsic value. This however misses the point of his statement about value. He is assigning value based on the item, individual of all other influences, having value. For instance crypto, it's value is assigned based on supply /demand premise. However it requires the interaction of 3rd party objects in order to fulfill its 1 and only utility purpose eg a vehicle of trade. Take away the tool required for it to fulfil its purpose (a computer) and its rendered useless for its purpose. Furthermore their is no other use for crypto which means all demand based Intrinsic value is speculative and 100% driven by blind greed. This is the common thread to all bubbles, be it tulips, beany babies or south Sea investment. Gold on the other hand has other utility uses (jewellery, electronics, etc) , it can be traded without the need for 3rd party objects and is finite. It is traditionally the item used to prop up the value of trade vehicles eg fiat and its only relatively recently that we have stopped requiring this for international trade. What changed? Simply put we are more trusting of one and another , it is no coincidence that even after its removal from many currencies trade dollars were minted for the sole purpose of international trade between un trusting nations and several Australian sovereign issues are rarities due their mintage being sent in whole to foreign states to engage in trade. Nowadays our plastic notes and junk metal coins are entirely designed and created with the sole purpose of enabling trade in a fixed ecosystem, outside of that system they have no value. Whilst they don't require 3rd party objects to be used they still hold the same fundamental purpose as crypto, to enable trade.
So why are crypto so valuable and my change has not increased in value? Simple supply/ demand psychology. As demand increased supply did not match pace and value increased. This is where greed and fomo kick in. Instead of the usual matrix of price eventually reducing demand to match supply it actually increased demand and subsequently the price follows suit.
Now we look that it's big weakness, the same mass hysteria that drove the price up can have the same effect on it. Now this is the point where alternative utility helps stabilise the price in most cases. Eg the shares of a company may do the same thing but the fundamentals of the company eg stock, property, intellectual property etc that form the company will stop the value dropping to zero unless of course the company has no value. Even south Sea shares didn't drop to zero as they had a viable business.
Gold will never drop to zero as people need it for just about every part of modern life eg medical science. Automotive. Telecommunications, household goods erc
What is to stop crypto from falling to zero other than the demand for it as an investment/trade vehicle?
Now correct me if I'm wrong but you seem to be arguing that modern markets require modern solutions and this is it etc.
But I argue that modern times, with modern trade practices are just 1 major catastrophe, war, etc from reverting back to traditional practices as trust is lost between nations and people seek to protect wealth beyond that history cycle.
Long read I know but I hope you learn to understand that we are not ignorant to crypto, we may not understand all the intricate details and information about it but we understand the overarching concept and find it lacking.
History is littered with examples like it and the biggest red flag is when people argue that it is the way of the future, you don't understand it so you are wrong about it and that others have made money from it so it's proven
