I noticed this video this morning: “[Monetary Reset. At least 80 central banks around the world are looking at digital currencies.](https://twitter.com/GoldTelegraph_/status/1383514308508733447)” and I can only wonder when central bank digital currencies are streamlined… could they be outlawed if they eliminate cash? I understand the decentralized component and its impossible in that respect, but I do think central banks could make it difficult on every day citizens to potentially buy in the future?
I am not looking to be attacked here, I am generally curious and I want to learn how this is not possible.
