> I do get that you don't "get" it, but I'll just say - I happily send and receive both BTC and ETH, and it is a night and day difference from sending using traditional bank accounts. I actually feel like I own the money, I can send it to anyone I want at any time, and the transaction settles in seconds. Last time I sent money via ACH, it took a solid 4 days (since I initiated on a Friday).
This is just a criticism of US banking, not 'TradFi' as a whole. Most countries have let you do the exact same thing for free or at a low cost out of your existing bank account, no overhaul required, for years. The EU has SEPA, the UK has FPS, Canada has Interac e-Transfers, Australia has NPP. I suspect you'd have a hard time finding a country other than America which doesn't support this.
... and the US has RTP for about half the population, and is getting FedNow for everyone next year. Not to mention Cash App and Venmo and so on.
This is a solved problem.
If you can even call it a problem. The thing is, if it were actually a meaningful source of friction instead of a talking point, it would have been resolved years ago.
I get it, moving money is boring unless the money is also a scratch-off lotto ticket.

This is also how Cash App and Venmo support instant transfers/deposits to a dollar-denominated bank account 24/7. You can do this via unlinked refund or whatever the new mechanism is. That's not crypto related, it wasn't developed for crypto but rather coopted (not just by crypto, but by Venmo and Cash App). That's just how debit rails work.
