Same here. I still don't understand what a wallet is in this sense
other than an app storing a bunch of tokens that haven't been redeemed

It's hard to say since there actually aren't any CBDC implementations.
My main concern was whether there was some new design significantly
different from the ones we've known about for the past 25 years, or
some way to prevent double spending in such a system other than by
having everyone agree on an authority to say which tokens are good.
The answers appear to be no, and the guy is confused.
