That’s the confusion. I’m only talking about technology.
You’re contradicting yourself. Visa and co. don’t own technology. As you wrote, the implementation is left to banks and financial providers. You need to decide whether you want to discuss banks’ software implementation or the schemes designed by Visa and co.
That could be done by just making a new NFC wallet app
You can’t just build an app that uses NFC, like you build an app that uses a phone camera. You need special agreements with Apple (or Google) to access their NFC chip. Visa and co. don’t have such agreements which makes their schemes limited and unattractive compared to D€.
Visa and co. don’t own technology. […] the implementation is left to banks and financial providers.
That’s exactly backwards.
The store POS system doesn’t connect directly to every individual bank that issues a card. They connect to Visa’s server which authenticates the transaction. They’re the network in the middle of the system that everyone else connects to. The banks just provide the account to transact from.

Then how is this new Digital Euro supposed to do NFC transactions if they can’t use the NFC?

That’s incorrect. Using push-up messages, the authentication is done in bank’s authentication app. If using SMS authentication, the SMS with code is sent and signed by bank. Visa and co. provide a bit of infrastructure and the messages between the processor and customer’s bank travel through their network, but this step is not essential for the transaction. For instance, processor could directly communicate with customer’s bank through ECB’s open banking API.
Then how is this new Digital Euro supposed to do NFC transactions if they can’t use the NFC?
Through regulatory effort. As part of WERO initiative it is already being discussed how EU will force Apple and Google to open their NFC chip. Visa and co. may piggy-back on that effort, but crucially, the regulation will be designed to facilitate implementation and adoption of WERO and of D€ and not the use and adoption of debit cards.
