It is though. I think you missed the part where it says you can't buy cryptocurrency from within Lebanon except with hard cash and from one of the exchangers. These exchangers have to get the cryptocurrency from somewhere to begin with. They mention that they wire the money to Nigeria and let someone there buy it for them.

Yes, money is geographically bound, which is why they need to wire it to Nigeria. But once cryptocurrency is bought with Nigerian funds, there is no "sending" it to Lebanon. That part is misleading. Sending is done not from one geographic location to another but from one owner to another.

Today's currency is all digital and is just a number, yet we say "we're sending it". You're taking the metaphor too literally.

Digital doesn't automatically mean that it's not geographically bound. If the servers that store it, banks that manage the accounts, state that issues the currency, and businesses that accept the currency are all geographically bound, digital currency is geographically bound. Crypto is less geographically bound by nature, because it's a distributed ledger. And the more successful crypto ledgers are globally distributed and this not really geographically bound.

That's like saying there is no "sending" an email to Lebanon. Sure you may be technically right but everyone understands what is meant, and in consequence it is equivalent to physically sending.
