"all real decisions are made in Brussels by non elected representatives"
The European Parliament, for instance?
I am not an expert on EU law. That appears to be one of many EU agencies that wield power over what laws are initiated and passed.
I guess the main point is - if the EU is deciding on the laws, and the national governments have little choice but to implement them, then what is the point of National governments?
Similarly in the US, our President will go to a G-7 meeting, decisions are made there, and the laws get passed both nationally and at a state level. Why do we need these "representatives" if they are are just "taking decisions".
