I'd take my EU strong from an economic point of view and without "yay sunday SEPA transfer" any day over the EU we have today. The EU is a massive failure and it's going to fall into oblivion versus the US and China: especially now that the EU voted to kill its main economy, Germany, by destroying german automakers (with the mandatory shift to EVs).
The EU produces metric shittons of rules and legislation which brings absolutely nothing of value to its citizens.
If anything I don't think the EU is something to strive for: on the contrary, it should serve as an example of what not to do. Even if this means no "yay, instant sunday payments".
