Every system has failures. That much is a given. The main issue is about scale of these systems and its failure modes.
The problem of "big" systems - whether the EU, modern day US where federal govt taking over power from the states or Communist China - is that it fails in spectacularly catastrophic ways.
This is why you get crisis like 2008 and Dieselgate. Both are instances of "too big to fail" industries, protected by the government and that in the end screw with the people that they claim to serve and protect.
So it doesn't matter that you are not defending VW, or that you are against Apple. The point is that by backing this ever-growing centralization of power and influence by one single political entity, you make the whole system more fragile and easier to be manipulated by those elites that you so loudly claim to be against.
> there must be a place where such failure doesn't happen.
Switzerland. Local governments rule over any attempt at centralization. Direct democracy. Individual freedom but without forced globalization and universalization of values. Not involved in any wars. NOT AN EU MEMBER STATE.
