Actually, some are. Some of them are scared of pushing so much the pitchforks come out.

The thing is, they can’t. It’s a unified market. Any tarrif against Denmark is by definition a tarrif against the EU.

Non-German but I am in the EU. Didn’t find it odd at all. Just assumed it was “flow market” in German.

There’s another factor that nobody mentioned: the sales tax in EU countries is different for different products. This allows countries to incentive or disincentivize different classes of products by ramping the sales tax up or down. Higher tax on junk food, cigarettes and/or alcohol, low or nonexistent sales tax for basic ingredients and medicine.

Interestingly, France and the Czech republic tax wine and beer respectively like basic food.
