You seem to complain about both the glass being half full and the glass being half empty.
As difficult as it is for a 27 member bloc (now including a couple of bad faith actors) to operate on the basis of unanimity, we are way better off with the EU in place. It's amazing how far something that started as an economic agreement among a handful of countries has gotten.
I hope there'll be a day when it'll be possible to reform the treaties to adapt them to the times.
