I read it the exact opposite way. It turns out that when you punish people with a decade in prison for lying, you can just operate on their word and verify later. I don't need a system that never gives data to a malicious user. It doesn't need to be Fort Knox. It needs to be logged and audited regularly and for people who abuse it to be punished severely. I'm sure there are lots of technical measures keeping my bank account safe. But, the greatest measure is that if you take the money the US government will throw you in jail.
