“Based on the concept of freedom advocated by Hayek, Buchanan, Friedman, and Mises, vaccine passports also violate economic freedom, which basically refers to the freedom to consume, produce, exchange, and cooperate spontaneously and voluntarily. They believed that “if one abolishes man’s freedom to determine his own consumption, one takes all freedoms away.” In other words, if coercive state actions violated or abolished economic freedom, then general freedom would essentially be taken away from individuals, including freedom of speech, freedom of expression, freedom of religion, freedom of assembly, freedom of the press, and intellectual freedom.”

“You will think like me or die; he says: You are free not to think as I do; your life, your goods, everything remains with you; but from this day on you are a stranger among us. You will keep your privileges as a citizen, but they will become useless to you. If you aspire to be the choice of your fellow citizens, they will not choose you, and if you ask only for their esteem, they will still pretend to refuse it to you. You will remain among men, but you will lose your rights to humanity. When you approach your fellows, they will flee from you like an impure being. And those who believe in your innocence, even they will abandon you, for people would flee from them in turn. Go in peace; I spare your life, but I leave you a life worse than death.”
