Also, I think it's just the reason that crypto-currency will fail.

If you trick me into an ACH transfer of 16 million, there will

a) Trigger some random human based audits at my bank before the money can leave (likely involve some phone calls)

b) Have actual recourse, like court orders to hold the funds at the other bank

c) Take some amount of time to happen, to allow for A & B

It's not perfect, and it has bugs.. but I would never store actual money of value in crypto anything.
