There was very little, if any freedom of expression or freedom of speech. Not very utopian.
Average citizens had their exposure to the outside world limited. Not very utopian.
Citizens lived in a very tightly controlled society. A society controlled by the government and secret police. Not my idea of utopia.
Even if the modern internet had existed then, it's doubtful that a citizen would even be allowed to come to a site like this and even have this discussion.
As far as the Stasi go, you can't just say "without them it would have been fine" because they are completely intertwined with that society. That society required very little or no dissent to continue and that is why the Stasi existed: To crush dissent and keep everyone thinking how wonderful their "utopian" existence was....
