You are looking at this on a surface, artificially separating essential needs (to breathe, eat, sleep, etc.) with non-essential ones (desires).
All needs, however, have a cause. Needs can be physiological or psychological. A need is that which moves you to action, that gives rise to your will to act, regardless if it is physiologically necessary (for survival) or not.
If we look at God as a being with no needs, essential or otherwise, then His will has no cause. In other words, God wills "just because," for no reason whatsoever!
And since we say that God the Father is without cause, it follows that everything He does and wants is without cause, for He is the cause of everything, including your needs and wants, as the Creed says "all things visible and invisible."
This is how lunacy about God is born and grows into pantheistic caricature of God in the Eastern religions or a fairy-tale deity of pagans and, apparently, some Christians .
There is another twist in this anthropomorphic lunacy that men have created about God: being Transcendent and Eternal, God has already thought of, created and decided on all things for all times and has nothing else to create or think or want. He did all the work, "thinking" and "wanting" from all eternity, before the world existed.
We can say this because we consider God to be perfect. Being "perfect," by the definition and meaning of the word, means to be complete or finished. Nothing can be added to or or substracted from it. Again, our words cannot adequately describe anything that is what we call spiritual; no amount of words will adequately describe God, just as no amount of words will describe love.
One must wonder if there really is such a thing as love. I am almost certain that if we would describe it or image it somehow, it would be a variety of loves, each suited to every man's fancy.
We cannot understand God, FK. We can only speak of God in human terms thinking of Christ. Not a burning bush, a rumbling volcano, the Sun, the lightning, etc., but only through Christ. That's why He says in the Gospels that we can go to the Father only through Him, through His image. That's why we can interpret the rets of the Bible only through the Gospels and ot the other way around.

Knowing that lurkers are reading I am going by common usages of terms and not allowing Reformed theology to be painted as holding that God has needs. That is what you were trying to do and so I must object. :)

If YOU want to say that God has needs that's fine, but I ain't goin' there. :) It looks like by your terms a "need" can also be described as something desired which the needer does not have. What does God not have that He desires?

I don't see any problem here. We just must be careful not to assume that the Creation consumes God. That is, He existed just fine before the Creation, and just because He created does not mean His existence has been damaged somehow.

I don't wonder about it at all, of course there is love. It is irrelevant that we can't know it fully. This is the problem with the all or nothing approach. One is always left with NOTHING. For some reason some people are dissatisfied with "adequate and good per God's will". They want it all or they want nothing to do with it. Their loss. But it also leads to bad theology, a theology without a base. I do not understand why these people shun true knowledge only because it is not exhaustive.
