What MLB said is correct even though I would have explained it quite differently. I believe that people inherently desire to have their individual dignity respected and to be free of fear and oppression. Life, liberty, and the pursuit of happiness, basically (noting the distinction inherent in pursuit
of happiness, which is defined by the individual and the government is relegated to a role of the minimal interference necessary for the individual to do so--meaning that crimes are punished but individual rights are maintained).
Democracy, though itself flawed and in danger of either paralysis or tyranny of the majority, is the best system we know of to ensure those inherent needs are met and inalienable rights respected. So people can need and desire those needs to be met without knowing what is currently the best means of their fulfillment. Should an even better means arise--and perhaps the Cardassians could come up with one for themselves that is not a copy of our system but that does not oppress or slaughter its own merely over differences in belief--then so be it. But I definitely will not stop believing that people inherently desire to have their dignity respected.
