Like true, kings can't claim divine right anymore, but claiming your right to rule comes from 45%-55% of a population that can't even point out Iraq on a map choosing you over the other guy is not much better.

The problem is, let's say we elect the first guy.
The next guy, we don't like. The next guy? We also don't like.

Without something like divine right, the populace and even the military will inevitably stop, pause, and ask "wait, why are we listening to this guy again?"

Hell, even in an elected monarchy, the second everyone realizes "wait, this dude is a dick, his dad was alright, but his granddad was incompetent, there's nothing special about this bloodline!"

It all falls apart right there because they'd wonder why to limit their options to a single bloodline living in luxury on tax dollars.

The divine right was a key ingredient holding the monarchy together because people in disagreement still respected a supposed will of god. 

You can't have a monarchy without somehow convincing people the bloodline itself is special.
