This is not completely true. The EU’s very economically successful pre-crisis state suggests that many of the decisions adopted by the EU are not “diluted to the point of being ineffective” and that in fact, EU works quite well. Although there are stark differences between individual member states they are able to overcome them and work meaningfully as a collective when progress is necessary. States are willing to sacrifice their interests in some areas if they get something in return elsewhere, or believe they will in the future. Therefore even if we accept the assertion that unanimous requirement is undemocratic, in a society with knowledgeable individuals, the veto is only used as a last resort. Thus what happens is that the allegedly "undemocratic" process functions as well as democratic process, but on top has an additional check or balance to prevent anything that is found particularly egregious to pass.
