I've never understood why the specious CBDC argument vis a vis BTC was used - but I can guess it's that the people who use it either don't like BTC, don't understand it, or most likely, both.
Anyone who knows anything about fiat knows that the only marginally good thing about it is that it does have a physical form, and that form, while still debased, is preferable to the controlled digital forms in obvious ways. Thinking a little more, you'd then see why they want to get rid of cash entirely. Putting all this together (this isn't high level thinking, but apparently people are either stupid or dishonest), the CBDC would be the worst possible world of fiat, because it's all about removing that last fiat roadblock (CASH) for complete surveillance.
BTC has outperformed fiat for over a decade with cash, the world would be worse with a CBDC, which would be inflated even more and of course more controlled, etc - how does that not make BTC even more valuable? It's funny how obvious all of this is to anyone who just thinks clearly.
The normie always seemed to be asking, as if it were a "gotcha", "They'll just come out with a CBDC and that'll be the digital payment system." Oh, you mean the one that will be debased more quickly and you'll be the most restricted by? Yeah, I'd rather have that than the money that isn't debased, I can take anywhere, and is permissionless. Great call, dude.
