Constructive argument? Just disband the EU as a whole, including all laws, treaties, contracts ...

Europe would be a much better place if the EU stayed what it was, a trade union of sovereign nations without any political power over the people.

How would this have worked in practice though? How could things like trade standards been harmonised or a common currency adopted without the trade union being able to do legislation?

And once you get there, you're no longer a trade union. Or a trading block, which is probably the better word since a trade union already means something else.

It still is. Countries can ignore EU laws if they want to.

I'm not sure what you try to achieve:

>For example, Poland was hit with massive daily fines when it was embroiled in a dispute over rule of law measures, as well as a separate case linked to environmental permits at a coal mine on the Czech border.

>The Commission is allowed to take these fines out of that country’s EU budget allocation, preventing governments from simply refusing to pay up.

The EU was never just a trade union.
