Of course. Some of them are awful and some of them are fine. You might as well reason that 'Apple is a corporation; corporations are essentially large bureaucracies; therefore anything produced by Apple will embody all the flaws of bureaucracy.' And indeed many people make arguments like this here on HN daily, arguing that large companies can't innovate because they're simply not agile enough.
It's not that bureaucracies can't be terrible, they absolutely can. But it's overly simplistic to argue that they're constitutionally terrible by virtue of merely existing.
Apple is a bureaucracy and I'm sure they make lots of bad decisions. But they're a much smaller bureaucracy then the EU, operating on a much smaller range of decisions.
What I actually said was that a very large bureaucracy operating over a gigantic domain and trying to make rules at very fine levels of detail across that domain would make bad decisions. Like, say, "we're regulating the entire economic system of half a billion people in very diverse economic circumstances down to the level of exactly what heads should be in what phone chargers."
