The EU was a certainty in a region that is hostile to change, wants big government, wants centralization, is suspicious of democracy, etc. Free trade would be a massive change, that is why it hasn't happened. The EU is basically the logical conclusion of European forms of governing.
I don’t understand how you can say that with a straight face, it’s such a contradictory statement
But the EU started out as an industry group, the ECSC, to limit competition in coal and steel (with the helpful side effect of making German industrialists who did very well under Hitler even more rich).
If there is any founding principle of the EU, it is that competition should be limited because the view of people who founded the EU was that economic competition caused WW1/2 (a very generous interpretation of Germany's role in events but one that was used because there were a lot of wealthy Germans who wanted to use the EU to limit trade...btw, the situation today is beyond their wildest dreams, it is has made a small handful of German billionaires very wealthy for no effort).
Somehow whenever European powers collaborate together it is framed as anti democratic, anti innovation, anti trad. Complete nonsense
