"Protecting" free trade from "bad actors" is just an extension of the state to control what "free trade" is from what it considers "bad actors".
Bad behavior does exist, but current technology far exceeds the capacity of bureaucracy to implement free trade, protection from bad actors, and most importantly Trust. The state itself becoming a bad actor is an increasing risk, which technology helps to hedge against.
I think it's important to remember that the Government IS PEOPLE. How are the people in Government any different from "normal" people.
They're not.
And so the people in government will be just as misguided, corrupt, fallible as any other organization of people. Technology helps us hedge against those failures.
