Don’t companies like TransferWise already do international payments electronically without the need for a blockchain? I definitely support lowering the amount of human labor required for payments, but I don’t see the need for many coal plants worth of computers randomly hashing a bunch of junk over and over again when a normal efficient server can do it.

Every bitcoin exchange I’ve used required me to physically write something on paper and show it to a human, so it seems like the human labor in the banking system is a regulatory issue, not a technical one.

Maybe to sign up, but to actually make trades it's just taking orders off the book.

Sure, but why do I need a blockchain for that? Can’t the service trusted by the government to enforce KYC regulation also run a normal commodity server to process transactions, without burning the earth?

I'm curious - what did you have to write? Is it just part of proof of identity, or something more?

Usually the date and name of the exchange, to comply with "Know Your Customer" regulations and fight duplicate accounts.
