(Arguing about engineering pedantries is, but that is something different.)
The main issue is that the EPP is basically in service of Germany and France lost a lot of influence when most of their deputies joined Renew, a party which is less well integrated in the European Parliament apparatus. That and France failures to even start tackling the structural reforms it needs obviously.
I don't necessarily think it is a good idea. I am a firm proponent of the EU. In a world where the other major powers are many times bigger than any individual European country, Europe cannot defends its interests when every member country is on its own. There are many issues with the current shape of the EU, but I see it as a necessary step on a path to something better.
And as for everything else, open borders, freedom of movement, standardisation of infrastructure etc. all can work without being mandated as well, if there is a common interest in them. The EU was designed, when there was no internet. Coordination can happen transparent and quickly without kafkaesk buerocratic institutions. And when there is no common interest to do things - then the EU in its current shape is not working so well either.
European defense structures rely on economic collaboration as well. There are lots and lots of multilateral weapon R&D programs that are only really possible because cross border collaboration between the involved companies is trivial because of the EU.
That is pretty much how I see the EU as it is. Maybe you are aware of the luxory of moving the whole parliament once a month between Bruessel and Strassbourg?
And calling my comment shortsighted is just inviting me to return the compliment and further degrade all debate btw.
I can't see how your vision is even the tiniest bit practical. It just ignores reality.
Or it acknowledges reality as it is. (I have seen lot's of europe)
I don't see a need for universal regulation of everything, which of course will get messy and weird.
I do see a need for standardisation of infrastructure. Track gauge of railways. No expensive roaming for telecommunication. Energy grid. Education certificates. Europol. Those things - and the debate there can also get exhausting for sure, but must not be.
But whether I will buy polish meat in what shape, or french cheese in what condition, is something I would like to decide on my own and don't need EU intervention. So no debates needed there, no complications of things that need no regulation.
I also don't see a need for a parliament that big at all, or actually a european parliament that has to physically meet in the first place. So expert comitees, that work on the bordercrossing problems yes - and then all the local state parliament can legalize the implementation.
Pretty much what is happening right now, just with less complications.
I feel this discussion thread has run its course. I said what I want to say and anything more would be pointless repetition.
My main point is and was, voluntarily coorperation beats forced cooperation most of the time. And if there is a will (even if it just comes out of the fear of external forces) - then even hardcore nationalists are able to compromise. Right now they use the EU to blame anything and block things out of general principle. Using the EU as a cheap scapegoat for own failures, but also for the feeling of it being imposed on them - and to this I can relate, even though I am far from being a nationalist.
