That's not what you're competing with. Your competing with a drivers license with a photo (not a great photo) and some countries have pretty easily faked drivers licenses, but others have drivers licenses in hard plastic with holographic features.
We're talking about the EU here, where the standard form of ID is an ID card with very strict requirements, including multiple secure features and an NFC chip with the photo and some other information.
You're competing with that for "I want to make sure the person standing in front of me is of legal drinking age" use-case, but for the remote KYC/age-verification usecases, you're competing with a photo of the document and/or a selfie.
Maybe bundling these under the same system is a mistake and they should be separate systems with different considerations; it would certainly help with arguments about it online ;P
I don't know about other countries, but here it requires your passport or actual drivers license, and a 12 or 24 hour wait, to actually activate the drivers license app.
The credit card doesn't work as age verification.
