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?
I may not agree with you about theological significance of CBDC, but I appreciate idea that implementing CBDC needed for them for implementing biblical prophecy much more than weird assumption that "CBDC is necessary for them to ban cash".
So, we could add another possible explanation for CBDC - they need it for theological reasons, as a part of their relogious antichristian views.
