You have not just separated the Kingdom of God from the humiliation of Neb but you have extinguished it!!! The tree represented both Neb's world rulership and the universal sovereignty of Jehovah God as expressed by the Kingdom of God as recognized by Bible commentators, expositors and the celebrated WT scholars.
The connection between the seventy years and the seven times is inherent in Dan. 4 as shown by the reference to it in the OG translation of that chapter and is explicit in the fact that both events began at the same time in 607 BCE.
The point of the dream was to show Neb that he was subjected to a far greater rulership of the Heavens, God's Kingdom or sovereignty.
