Admittedly I didn't watch the video because when I read the title this thought immediately popped into my mind and answered the question posed. If we were truly free we wouldn't have to ask for some government's permission to travel into space- just ask Elon Musk. And that fact really irks me. Heck aside from an ultralight you can't even fly an aircraft without the FAA's permission through adhering to their regulations, licensing, registration, and flight plan requirements. The best slaves are those who of course don't even realize they are slaves. I'l know I'm free when I do not face the threat of force being used against me to travel into space without first being granted permission by some entity comprised of other humans that demand I ask their permission first.
