"cold hard cash in the bank" is digital as well nowadays. Money is essentially tokens and has become increasingly abstracted from anything tangible. We still tend to treat money as a thing of value in itself, but it isn't. It's just widely accepted tokens. Numbers in a digital wallet are as "real" as other tokens unless the tokens themselves are made of something that has some value (which is not connected to the face value of the token, e.g. a metal coin has some value as scrap metal but usually not the same value as the face value of the coin).
NFTs are just another example of tokens. They have the advantage of not being possible to forge and the disadvantage of not having any powerful organisation backing their value.
