Why would being physically in a bank be needed?
Interbank transfers work the same way regardless of country ( with the exception of sanctions - you can't wire money to Russia or Iran just like that), over the SWIFT protocol with an IBAN and BIC. Usually you pay a fee for the transfer and currency exchange - some banks abuse that, some are competitive.
I have transacted millions in crypto and wire transfers. Banking with crypto is like the 1970s - exorbitant fees. To do anything useful with it I have to offramp to fiat which drum rolls ends with a wire transfer.
I don't think I've ever wired money in my life. I guess I never needed to. And the few occasions I needed to send some money internationally, I've simply sent crypto, used Western Union, or something like PayPal or Revolut.
I’ll admit that the crypto UX is faster with just entering a destination wallet address. It would be good if banks could adopt QR codes to provide similar experienfe.
Sometimes you get charged a fee, but many institutions will waive that (e.g. Schwab) if your balance is high enough.
