> Humans generate decisions / text information at rates of ~bytes per second at most

Yes, but the consequences of these decisions are worth much more. You attach an ID to the user, and an ID to the transaction. You store the location and time where it was made. Ect.

I think these would add only small amount of information (and in a DB would be modelled as joins). Only adds lots of data if done very inefficiently.

Why are you theoretising? I can tell you from out there its used massively, and its not going away in contrary. Even rather small banks can end up generating various reports etc. which can easily become huge.

The speed of human decision has basically 0 role here, as it doesn't with messaging generally, there is way more to companies than just direct keyboard-to-output link.
