At what point in human history were markets ever free of state guarantees, security, international law, labor control and regulation?
Freedom is always a matter of degree. At times they've been more free, at times less. Why do you ask?
Your video celebrates an economic system where power is allocated in an unequal and unstable manner yet, through the mythological invention of an "invisible hand", guarantees the "freedom" of those subjected to it. You need to spend a few years in a Nike sweat shop, or a Chinese graphite mine.
I didn't watch the video, but would you
really want an economic system where power was allocated equally? Where the town drunk had just as much say in what we all do for a living as more prudent, thoughtful people?
Free markets are decidedly about distributing economic power
unequally. They allow us to vest the power to direct labor and resources with those who provide us with the goods and services we want and need. It's hard to see that as an inherently bad thing.
