If it's that simple, if you can just make decisions by fiat based on some set of core principles, no matter what the people say, then you don't need to take account of the popular will at all. Just have a government of philosopher-kings.

In reality, it's in no way the simple ground truth that Turkish coups have uniformly sought to achieve "greater democracy". What they are in fact is a terrible misfeature of the Turkish system; a way in which Turkey joins the ranks of Pakistan and Egypt on a faster or slower arc towards autocracy. Which is the other word for "democracy that remains democratic until the people do something that make you uncomfortable".
