I disagree. The IMF has repeatedly stated they would like to see banks continue to act as retail financial services providers. Also, if a CBDC were to operate on a blockchain, with one chain per CB, then that could bloat very quickly.
For example, just as Tether is the issuer of USDT coins on various networks, so a CB could issue a CBDC through various big bank blockchains.
This thread also interesting:
Chiming in, Bitcoin maximalist Jimmy Song said the BTFP effectively nationalizes the banking sector, making a CBDC the “natural progression” from here.
I don't even think that's necessary. A CBDC can be run as a closed shop POS with some big banks as validators.
All of which doesn't mean I disagree with the central premise that these attacks on some banks are very thinly veiled attacks on crypto; I just think the consequences expressed are not quite right.
