I have a very strong feeling that @paf0@lemmy.world is being downvoted here, not because they make a bad point, but because they phrased it in terms of cryptocurrency which immediately triggers negative reactions from everyone.
What OP has proposed is neither novel, nor a terrible idea. In fact, economists call it a central bank digital currency. And yes, some countries have adopted it. It’s usually not run with a blockchain, but that’s because if you have a trusted central entity to run the system, that being the central bank, a blockchain is inferior in practically every aspect to a normal relational database. That’s why all current CBDCs still use fairly traditional accounting systems.
Your use, however, of the terms “real money” and “fake money” has, I believe, the effect of shutting down intelligent conversation, rather than encouraging it. “Money” is a social construct. “Real money” is whatever the Government declares to be “real” and that the population is willing to use. It doesn’t need to be physical money. And it is unquestionable that in the countries that have adopted the legal framework that allows their central banks to issue CBDCs, the money so issued this way is as real and legally equivalent to paper banknotes and metal coins.
