A CBDC is still the local fiat currency. In which case, it isn't really a replacement of international financial services like Visa, Mastercard, Paypal, and others.
That's correct. But having "government approved" wallet(s) for the CBDC is just a tiny step forward, and then the people will be able to pay with that wallet via smartphone, instead of paying with Google Pay/Apple Pay with the Visa/MasterCard cards enrolled.
And I guess, although this may highly vary from one country to another, a CBDC implementation does not eradicate payment solutions like the ones mentioned
Indeed, my use case works primarily inside the borders a certain fiat currency already works as legal tender.
To my mind, and based on observation, the government would continue to accredit third party payment providers.
Then they may have no "selling point" for those CBDCs. I mean the shops will have no benefits to accept that, the users will have no benefit to use that, only the govt has benefits, from surveillance and control to less money spent to issue the old/existing "paper".
As a matter of fact, I don't believe that a country implementing a CBDC would only allow a single government-operated wallet. It's likely that there'd be a number of them, privately-operated mostly.
If so, I fail to see what entity can actually benefit of CBDCs.
