Do that and you will be ass raped by stronger powers in record time... if we don't start a war in eu amongst ourselves.
The eu was established as an economic union trying to prevent war in Europe and it has been very successful in that. Going the other way would probably cause havoc. Look at Hungary and Slovakia even with war on our doorstep.
I am of the opinion that the EU needs to federalize. It needs to look as one country from the outside, while having independent countries on the inside. The goal here is not to be overwhelmed by the economic and military might of china. Build up resiliency and self sufficiency and keep democracy alive, which seems to be on the decline everywhere.
The question is how not to end up in a totalitarian regime, which chat control is about. It doesn't and it never will be about the children.
The EU is necessary.
