This is why PayPal for the longest time made it really clear that "we are not a bank". So that they wouldn't be subject to those regulations and could suspend accounts and keep the money.
They kinda can.
In other words, you leave the bank-branch with a big sack of cash... And then your car is impounded because you can't prove you're the owner or your license expires, and you'll live in a tent in the woods because landlords can't verify your credit/rental history, etc.
The important part is that they can't just close your account and keep everything.
Meaning the requirement is just Apple or Google account with extra steps.
I strongly doubt the US would mandate this, but could see the EU doing so. The technical primitives exist and implementation is straightforward. Without a law, this will not change, there is no incentive for it to change.
With which states?
I'm I'm a citizen of two and live in the third, potentially having eSIM of the fourth?
The US Login.gov idp is about to roll out identity attestation using your state issued government credential provisioned in your mobile wallet (mDL), for example. I can perform identity proofing and attestation with my digital driver's license and passport in my iPhone Wallet today (at a TSA or CBP checkpoint, for example). Why can I not login to Google and Apple with that identity? It is federated identity management fundementally.
