Why do you believe that those of us who are cognizant of the warnings God gives to the believer in the Church epistles and live in light of the truth of God's Word concerning those warnings believe that "our obedience to written laws are necessary" for "salvation and righteousness"?
Has it ever dawned on you that the reason believers heed God's warnings have everything to do with abiding in the Lord Jesus Christ ... warning us to not be drawn away from Him? If we pay no mind to God's warnings to us (you included), we (you included) may just find the works of the flesh exhibited in our lives. When we abide in the Vine, the result is "much fruit" ...
John 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
