Most of those citizens don't speak any of the languages that the EU operates in. And the EU only translates the result of the legislative process, not the process, so participating in Polish or Greek ... or even French ... is almost impossible. Eventually the outcome of the whole process is translated, but that's it.

And starting next year there will be exactly 0.9% [2] of the citizens that speak the language that the EU government conducts itself. Now it is 13.9% [1], which is not exactly a good number. As if it wasn't already a huge problem that the French and German governments essentially control the EU.

Combine that with the fact that large blocks hate eachother. Like famously the French and German governments, for example, but those are hardly the only examples. Some blocks have actually recently had shooting conflicts with deaths (the Catalan and Spanish governments, if you're wondering, and yes, both have representation, even though the Catalan government gets no representation in the commission or council, the only institutions with real power in the EU).
