Yes, we're not on the same page because you believe that Paul, in saying we have righteousness now, means that we have *sinless* righteousness now, when Paul only indicated we have access to a righteousness that *saves.* All men have a measure of righteousness, but the only righteousness that *saves* is the righteousness that comes when we embrace Christ as Lord. Then we have righteousness coupled with forgiveness, enabling us to inherit eternal life.
So saying we have Christ's righteousness is *not* saying we have *sinless* righteousness. It is only saying that we have righteousness that *saves.* It is a righteousness that we have access to, enabling us to war against our passions and overcome our sinful inclinations. But we are not rid of the Sin Nature until we inherit our sinless bodies at the resurrection, or simply when we die.
On the contrary, our new life in Christ does not eliminate the body of sin that we live in until the resurrection. You sin, just like every other human being on the planet, Christian and non-Christian. To say otherwise causes you to call God a liar. I didn't say that--the Apostle John said that in 1 John 1.
No, you're still in the Adamic, sin-cursed body of flesh. You just aren't living in the flesh if you're living by the Spirit of Christ. What Christ accomplished at the cross was the right to give you a righteousness no longer subject to termination. Not even your death will be able to cancel your righteousness, since you are now qualified to rise from the dead.
Christ did those things to show his indifference to the claim of Satan upon our lives. He died, and no longer counted the sins against those who have sinned against him, assuming they repent and receive his life in place of their own carnal wishes. This does not re-make us instantly, though it does give us this righteousness instantly. But the resurrection and the disposal of the old body of sin comes later. Sorry you can't see that!
I see this 1 John chapter 1 and 2 as we are either walking in our old dead nature if we are into sin. Or we are walking in the spirit if we are not into sin.

Chapter 2
1 "My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:"

Romans 7:5
For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.
Romans 8:9
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you...
