The intrinsic value of gold (i
e. for jewellery/electronics uses) seems likely to be much less than the current market value of gold. So I don't think those limited use cases are a good explanation for gold's value.
Also, Bitcoin was not necessarily designed to replace every fiat currency for every single everyday spending use case and it's a strawman to imply that if it can't do then it's "dead on arrival". There are plenty of important possible use cases which don't presuppose the collapse of all fiat currencies.
Finally we don't really know the volatility of Bitcoin in the long term. It hasn't existed long enough. Looking at the price behavior in the first decade of its existence is not likely to give you a promising picture of any new asset class.
