If our human nature at birth is "" then whether or not you call that "the husband of Romans 7" or "the flesh" it amounts to a fallen human nature that desires sin (clammors for it) as you say.
Look closely at how clammoring to fulfil it's lusts was changed to "Clammoring for sin". There is a difference, a huge difference.
My flesh wants to be full, feel good, be the right temperature, ... These are not sin. We were put in a body of flesh by the Creator. He saw it was good. These lusts are not sinful. Look at church history and see how the ascetics tried to impress God with their ability to "crucify themselves". Oh how foolish we say yet the same is going on today. Look at how we try to gain victory over sin: self help psychology, accountability partners, will power, letting people check our internet history, ...
The Puritans became popular because they were "holy" people. However, if you look at their methods you will see the flesh controlling the flesh. Luther was frustrated by the lack of holy living among "his" people so he tried to start preaching "law". Not OT law, but what I call christian law. This is why zealots (not according to knowledge) like legalism. It gives them things to do.
A baby is born and wants to eat. That is good. A baby comes out of a warm cozy atmosphere and into a big cold world wanting to be wrapped up and kept warm. That is good.
A baby is not born hating God. It doesn't even know there is a God. It just wants to live.
God wants us to desire Him, but our flesh couldn't do it even if it wanted to. It has no ability to connect with God. God is Spirit and we must worship Him is spirit and in truth. There is a battle going on. It is talked about in Romans 7. We need to be freed from the body which wars against us. There will never be a man that will live teir entire life choosing God over the lusts of the flesh. They need only one time to choose "pleasure" over God's ways and they have sinned.
Paul was confronted with the Law. His mind new it was from God and desired to keep it. He willed to, but his body kept serving sin. That is not salvation, but it makes one see that they are a sinner. (7:25 So then with the mind I myself serve the law of God; but with the flesh the law of sin.)
Rom 8:3 "For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit."
The flesh likes the law in a perverted kind of way because it can at least try to keep it. It cannot worship is spirit and in truth. That is why a lot of people still like the law, they can do it in the flesh (or think they can).
I don't think God intended to leave Adam in his body of flesh forever. Having a knowledge of good and evil and living in a body of flesh is not the best way to exist. Knowing this, God sends Christ, the second Adam. It is through him that we can be free.
Romans 6:6 "Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin."
Col. 2:11 "In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ"
An ye are complete in Him. Walking in this "Truth" is what sets us free.
