Wouldn't gold's physical nature be a real weakness because it could cause a "centralization in vaults" problem? How much gold can an individual legally own and store in your homes in your country?
Then there is Bitcoin. It is virtual, and it opens a world of private key ownership, and therefore, true sovereign ownership of private property which governments cannot control.
Some see bitcoin as the tool outlined in Satoshi Nakamotos whitepaper: they see it as a peer-to-peer form of electronic cash usable in all types of situations. Others believe bitcoin should not be usable; instead, bitcoin should be exclusively designed as a store of value.
So it all depends on our perceptions and use case at a particular point in time.
