Your argument leaves out the key part of Paul's claim. What Paul is arguing is that "There is NOW no condemnation". His whole point is that People were condemned before, regardless of their relationship with God but not condemned now for those in Christ Jesus.
Earlier in Romans Paul establishes what the condemnation is in reference to, and it is specifically in regards to Adam's sin rather than this "Satan and his angels" nonsense.
5:18 Consequently, just as one trespass resulted in condemnation for all people, so also one righteous act resulted in justification and life for all people. 19 For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous.
Your clam that "Condemnation being reserved specifically for those who reject God altogether." is simply not supported by the text, and is specifically contradicted by Paul.
