You can use cash after they introduce CBDC as it will not be outlawed so that would mean that anyone could skip CBDC which makes it irrelevant for purpose people make it to be (tracking, blocking etc.)

And if they plan to block cash in the future, why would they want to introduce CBDC when they could introduce whole programming and control in current system. It's like extra step for no real gain as it all depends on removing cash.

As i said before, every scenario that includes "control" or "blocking" that i ever heard simply does not stand on it's own in current proposed law for CBDC.

There are some that really make sense for EU. For example, they want to skip Visa and Mastercard as payment providers which are US companies. In current political climate that makes way more sense than anything else.

Maybe they will kill two birds with one stone, make alternative to Mastercard and Visa and track and block, i don't know, i just want to express that for most scenarios that people are talking about, they do not need CBDC i don't say that CBDC is good and i agree that it allows way too much insight in the future, once cash is dealt with (and i am sure it will be dealt with sooner or later). It just looks like an extra step for tracking and blocking without any benefits for tracking and blocking.
