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?
But they have the complete history of every transaction. The innocent spare parts worker was effectively defrauded by the conspiracy theorist using illegal tokens (they can trace the chain of every token). Thus, they can make it so the conspiracy theorist now owes the spare parts worker the $1. If the conspiracy theorist has no tokens (because all of his tokens were made illegal), they could take the tokens from his family to pay his debt, or make him into a permanent "debt slave" of his "victims" until his pays back his debt (this could also carry to his family if he decides to kill himself).
But the government cannot retrospectively identify every banknote used by the conspiracy theorist. With the CBDC, since every token is tracked, they know the id number of every token ever used by the conspiracy theorist. They can identify these tokens retrospectively i.e. once they identify the conspiracy theorist, they can find all his transactions and the id of all the tokens he used. They can then invalidate these and punish him as above.
