For one that those things were pre 1993....
You attribute stuff to the EU, that is not from the EU.
Il ignore that it was the EC that was formed in 1993, not the EU, because it is irrelevant

The formal name of the Maastricht Treaty is even "The Treaty on European Union". It's the foundation document of the EU and includes agreements on the use of a single currency.
It feels like we don't share the same definition of concept of "EU" somehow? When was your EU founded and how is the EC not a predecessor and integral part of it?
