An important feature of (some) crypto stablecoins is that they function like cash.

Cash is fungible. And cash in my wallet is not subject to being frozen like a bank account.

One can argue the merits of a digital cash for society. But a crypto-based digital cash is fundamentally different from a digital bank-based payment system.

then we continue to use physical cash. a $10 bill still works when the power goes out

I did find myself without barely any cash during Spain's blackout and that made it really stressful. It made me value physical currency a lot more.

Now I wish digital payments didn't require a server/ledger connection at all, but I understand that would risk double-spend attacks unless all the computation could be fully trusted, which we can't even guarantee for existing card payments.
