Ok, so I can't throw a van full of computers in the back of a truck in the Czech Republic, drive it to Estonia and sell it in the local market with no customs fees? (hint: yes I can). Nobody was talking about free trade outside of the EU, when the whole point of the single-market was to prevent war in a region that had not seen total peace for more than 20 years for the preceding 2,000+ years: the point becomes much more about that region. 70 years without a major war is absolutely incredible. Even "the long peace" had minor wars. The EU does promote free trade, and signs deals when it can, and I was talking about internally anyway since that's whats relevant here; the EU is made up of countries that no longer go to war with each other. Which is the entire point.
