IMVHO the issue is more on the mere understanding what money is. I suggest rediscover a small scene from a Colombian movie (witch is nothing really interesting IMO beside that small sketch): El Concursante, here the relevant part: https://youtu.be/WpGhcDg7IJ4 https://youtu.be/WpGhcDg7IJ4 that's the more clear and simple compact explanation of the nature of money. In short: a currency is a symbol, a unit of measure, a cohort of people accept in place of something tangible. It reason is that we can exchange goods one counter another in the classic barter BUT sometimes two party have something to exchange that mach sometimes no, the general symbolic unit of measure solve that issue. Having understood that we can comprehend that actual issue is not the banking systems with a central bank but the fact that such bank is private and do not generate unit of measure for the public according to current public needs, they loan them treating money as the substrate of anything instead of the inverse. Understood that we comprehend that the solution is not finding new unit of measure of some kind but made central banks public and private banking without any seigniorage or power in the central bank. Cryptos are surely the ideas Big of IT have to ingest banking sector under their control, and banking sector understand that well, see for instance https://voxeu.org/content/banking-disrupted-financial-intermediation-era-transformational-technology https://voxeu.org/content/banking-disrupted-financial-interm... and https://voxeu.org/article/digitalisation-and-future-banking https://voxeu.org/article/digitalisation-and-future-banking they are even worst for the public because with physical cash limits are artificial, with cryptos the need of iron and connection are practical.
