In the UK we can do that without the blockchain, in many situations, thanks to the real-time payment system [0]. So for me, a normal bank transfer is free and easy, whereas every time I've tried to do something involving blockchain it's meant delays, fees, and messing around on shady-looking websites.

I take the point that in other places the norm is a lot worse and blockchain systems are producing better results, but it won't be long before banks get their act together and improve their services to match modern expectations (for fear of becoming obsolete), and then the blockchain competitive advantage is gone.
