Does this conclusion necessarily follow?
Personally, I don't think so. Here's why--Everything He created is good. Why? Because He says it is. However, what if He decides that destruction of His creation is also good? After all--He did destroy Sodom and Gomorrah, the Canaanites, etc. Granted--in those examples, He was destroying that whach had fallen, but the concept remains the same. What is "good" upon creation, may not remain "good" throughout history, thus requiring its destruction.
This degradation is (obviously) due to the Fall, but it still exists.

This is an important point.
"Good" is a convertible term with "one," "true," "beautiful," and "being." So all things that exist are good, at least in the fact of their existence. In this sense, even the devil is good, since he possesses existence.
God Himself is goodness and existence itself. His Creation participates in His goodness and existence. "Goodness" is not a label attached to things, but what all things are, at least inasmuch as they exist.
However, what if He decides that destruction of His creation is also good?
This is the crux of the issue. Logically, can a just and good God annihilate that which is good? This seems like a contradiction to me.

I think there are two issues of justice here, God's justice with regard to sinful people and God's justice with respect to His Creation. As Christians, we know that God does not annihilate any souls, even the souls of those condemned to hell for eternity. But what should be the fate of the world? Certainly, we know that Creation became disordered through the sin of Adam, so Creation itself is fallen. So the question arises, which act is more appropriate to an all-good God, the annihilation of His fallen Creation, which possesses goodness in its existence, (at the very least) or the transformation of His Creation?
What is "good" upon creation, may not remain "good" throughout history, thus requiring its destruction.
Is destruction the only option? Does it follow necessarily? Or is the transformation of His creation more just, noble and appropriate?
