The core defining principle of the EU is free movement of goods.
The Treaty of Rome 1957 set out “The activities of the Community shall include . . . the elimination, as between Member States, of customs duties and of quantitative restrictions on the import and export of goods . . .; the abolition, as between Member States, of obstacles to freedom of movement for persons, services and capital.”
The 4 freedoms are? ...people, services, capital and goods?
So apart from people all things essential to a customs union; and if need to make trade deal etc having people move freely makes sense.
So what is the EU? It’s based on 4 freedoms which are heavily trade based.
