Maybe explain that to Paul because he was writing to Christians being dead to the law - how can Christians be dead to a law that supposedly ended at the cross?
The Law was completely fulfilled, completed, at the cross. There is no more sacrifice for sin to be made. If the Law was still in force in God's eyes, at that time (the writing of Heb.), further sacrifice would be called for.
Just because there were some who chose to live under the Law, doesn't mean that the Law covenant was still in force in God's eyes.
Is that what you are saying, that because men chose to live under the Law, that God had to live by it also, even though it was dead, ended, in God's eyes?
Rom 7:4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
Paul is contrasting the Law with the new covenant and how the new is better. But there were some teaching that the Law was still in force at that time. Paul is explaining that the Law is dead, that you cannot return to it as Christians.
Also explain how in Hebrews that is it written on whatever they wrote on back then that the old was nigh unto passing if it passed at the cross.
Heb 8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Paul is quoting from the OT, Jer 31:31-32, Heb 8:8-9, at the time of the original writing, they were still under the old covenant, waiting for the new to begin. At the time the statement was made, originally, it was old and ready to vanish. Paul was stating that it had passed as a fulfillment of prophecy.

The old covenant ended at the cross, the new covenant/kingdom began on Pentecost.
Some tried to hold on to the old covenant, but it was dead.
The temple still was there, but the veil had been torn "...from the top to the bottom." Mk 15:38.
But now you say that maybe the Law was still kind of in force, that maybe the veil had a few threads still hanging together until 70 AD?
It is impossible for God to be enforcing the 2 covenants at the same time. But that seems to be what you are implying.
