For example gold can be used to make jewellery etc. USD can be used to pay taxes. Shares might yield a dividend. Any physical object could have some use. Crypto has nothing.

You keep saying crypto has no value, but that is false. It may have no value to you but it has value to other people. There is no such thing as 'objective value', which is why there is also no such thing as 'inherent value'.
