Why don't just copy what's in use in other countries? For example, sending and receiving money in the EU is pretty simple, you only need their IBAN, and maybe their name (AFAIK some countries require it). I'm not even aware of what's going on in the background, but from the user perspective its easy and free.

Well "what's going on in the background" is exactly what's being discussed here. End users will never be exposed to any of it.
