> It's written into the treaties that this will not be so.
What exact treaty are you talking about, and what does it verbatim say? I've heard this so many times before, yet no one is able to link to concretely what they refer to. No texts I've seen has called for the dissolution of nation states in the EU or any of the other political structures.
The goal of ever closer union appears in both the Maastricht Treaty and the Treaty of Rome.

>RESOLVED to continue the process of creating an ever closer union among the peoples of Europe, in which decisions are taken as closely as possible to the citizen in accordance with the principle of subsidiarity,
Now you might say, ah! This text also says that decisions must be taken as closely as possible to the citizens. Yes, the treaties do say that, the EU just doesn't do it. Of course it makes no sense, the claim about subsidiarity is in direct contradiction to the first part of the sentence, you can't be both in an ever-tightening political union and also have decisions made by local governments. In practice the first part is chased and the second part is ignored. EU decisions are taken in Brussels - far away from the average citizen - even about many issues that don't need to be decided there.
If you want to understand the real origins of the EU and where it's going, you need to read the Ventotene Manifesto. Written during WW2 by a group of imprisoned Italian communists, it calls explicitly for a communist revolution that would unite all of Europe. Although it's insane to do so the EU today reveres this document and credits its primary author as being a "pioneer of the EU":

and a "founding father of the EU":

Spinelli's document can be found here:

It says things like, "In order to respond to our needs, the European revolution must be socialist" and "By this dictatorship of the revolutionary party a new State will be formed, and around this State new, genuine democracy will grow". It goes on like that in quite some detail.
A sane and moral EU would put as much distance as possible between itself and people like that, but they do the opposite. Spinelli was one of the primary authors of the "Draft Treaty for establishment of the European Union" in 1984 that led to the creation of the EU later via the slightly modified Maastricht Treaty. He became one of the first members of the European Commission and was a member of the European Parliament.
