By destroying the nature of the bank, the system of fiat would probably collapse, or at least, be reduced to what is seemingly a useful but useless asset. The first thing that cropped out of my mind when banks were said to be gone would have been the era of the past, trading items for items instead of using cash. After all, the government regulates the supply of fiat cash BUT the central banks are the one responsible for producing the fiat. Sure, you could ask someone else to create it, but the process required to create it is also connected to banks purchasing assets or lending money to other institutions. There's also an issue of Central Banks being the one most involved in regulating the inflation of the market and growth of the economy

In the past.What do you think why the words "past" were used? It was because something better came up, which was the fiat system, so using it as an argument to defeat the one that changed it seems kind of weird imo.
