> "Remotely send money" is a super hard thing to do. I literally just struggled for a month with a transfer that included 3 countries, none of them is English speaking. It required...
But this only shows that some (many?) places are woefully behind on online banking, not that blockchain is required. I can transfer money abroad from my bank account to, probably, yours (do you have an IBAN account number?) with just a few clicks more in my online bank than a domestic transfer. If the banks in your target countries caught up to that (not incredibly advanced) standard, you could have done that too. And I'm fairly sure neither my bank nor the ones of my recipients, nor the systems in between them, use any blockchain whatsoever for this.
So not a valid example that blockchain is actually needed.
