The problem with coins/notes is that who makes them (if there is too few of the required type)? With the a centralized authority (government) making them, there is some control on fakes and accumulation of wealth (if you allow private parties to make them, there is no regulation on fakes/hoarding).

But the government can choose to demonetize cash at any time by declaring them to be of no value from so and so date (something like this happened in India a few years ago, and possessing demonetized currency above certain amounts is illegal). Most of the cash is returned to government in exchange for bank transfer for the same amount. Very few coins/notes will be left. If there are very few number of notes/coins of the required type, there is too few for everybody to have, so those who don't have it will resort to barter instead. It is also difficult to make everyone agree on the value of a certain type of note/coin without centralization. And with gold/silver, how do you verify if it is fake?

The problem of fakes and centralization is why crypto was created. Any person can mine their own cryptocurrency if they don't have any (no need for centralized printing/minting). I agree blockchain tech has many problems, but the idea of using cryptography to authenticate is quite sound. There are now multiple alternative technologies in place of blockchains.
