Sweden have had Swish for ten years now, long before crypto was relevant. It is ubiquitous, I believe 90% of the population uses it. It was implemented by a consortium of the largest banks in the country. And it's not only Sweden: other countries have similar systems. I believe the use case and the need of instant bank transfers was long known, and that crypto was never a catalyst for the need to be aknowledged. That the US is generally slow to roll out this kind of national standard is mostly due to politics and general aversion to government work, not because the US waited for crypto to make the problem "known". Relatively very few people use crypto for any sort of real-world currency transfer.
