I'd like to see your other examples of God speaking this way anywhere in the Bible.
I think Arach was taking the perspective that it might be a common idiom of the people that wrote the Bible. Either God was really about, and Genesis was written in a divinely inspired way through the idioms of the time or God doesn't exist and it merely reflects the way the author(s) spoke or wrote.
You mean that God likes to imitate the earthly kings? Do you mean that He listens to the kings of the world and thinks its pretty cool the way they talk.
Or perhaps earthly kings listened to the way God spoke (or was claimed to speak), and since they are meant to be in power with the grace of God they imitated Him.
