This entirely depends on what uses it. If every website on the planet starts requiring you to attest to your identity to view the site, then yes. If it's actually just banking and e-filing taxes, even if you're doing that over Tor from a burner laptop running Tails on library WiFi, the activity is attached to your identity anyway.

But if it's actually just banking and e-filing taxes then you don't need a "digital National ID" you just need a login to your bank and one government website, which have no real reason to even be the same login.
