The divine right of kings was a farce as well. The power of the nobility layed in the contracts of armed men, the people that armed them, and the peasentry that worked the land to feed the others. The invention of those fedual contracts being ordained by God was a helpful enforcement mechanism based on myth making to justify it.
Regularly still the divinity of kings was tested and found lacking compared to more men on more horses with more spears and more armor.
Myth is good, we are narrative driven beings, but don't mistake the parable for the certainty of steel or the weight of gold. The constitution of the US is actually written as such too. It is not, by divine will we are free, but rights we are born with must be defended with greater force then by those that would violate those rights.
Maybe I should clarify I'm not saying the ideals of democracy and human rights are wrong. At all. I am saying that treating the existence of those ideals as enough to manifest them is naive and ultimately failing to maintain power to defend and uphold them is the same as giving up on them.
