Reading all kind of CBDC propaganda and those who are clearly against CBDC I absolutely can't get something real from that stuff.
Every single feature/option/whatever of CBDC could be implemented using current bank card/account system without single problem. Everything, from any restrictions to programming buying power or whatever. Every single thing that somehow connected to CBDC in everything written about it and posed as threat/advantage by whatever side is a question of a few minutes scripting in bank computers over current card/account system.
So, what is the real point of pushing CBDC crap by TPTB? Money laundering? Creatiing a base for some other narrative unknown yet, like kind of cyber threat fearmongering? What else? Anybody?
You could always go direct to the local farmer and buy some food with cash. Or buy from your neighbor who keeps chickens or a stock, or from some cash only simple market with no phone or wifi - I did it out of disgust when businesses would not take cash. Such markets became more popular during recent times just for such reasons.
To lock you into one area, they had deploy police and barriers - it was expensive, messy, unreliable. I was able to be nice with police to go where I wanted to go, or take a smaller road they had no resources to police. With CBDC it's a mouse click, and done - no way around it unless you bring a picnic and tent. But then CBDC is not the only front of attack - think of the English 15 minute city that tracks your car reg if you leave your area.
You even don't need cash for that if you have something useful for farmer.
Just like with card/bank account.
