What you say is very interesting, and I understand hat it comes from many years of thought and study on this question, but the written Law, like the tabernacle, is a shadow of the Law of Christ, not the Law of Christ itself.
So I'll give you an example of what I mean. I'm a Gentile, but since becoming a Christian, and even though I do not observe/celebrate Pesach (Passover), I have over time developed a love for Passover, and the meaning of Passover as it relates to Christ (the cup of Redemption which He took when He said it represents the New Covenant in His blood, etc). The same goes for The Day of Trumpets (a.k.a Rosh Hashanah) and the feast of tabernacles, and I deeply appreciate the meaning of the feast of firsfruits, as it relates to Christ, Pentecost, the Day of Atonement, etc.
I don't feel the need to religiously observe any of these appointed times (meaning I do not believe I need to "obey the law of Moses"), but I believe that they are far more meaningful than the feasts the Church replaced them with, since hey are, indeed, as the Hebrew calls them,
moedim (God's "appointed times"). So much of what Jesus said about the gathering of the harvest etc comes directly from these "appointed times", and they coincide with the agricultural cycle in Israel.
I observe Christmas and Easter with my Gentile family because I'm a Gentile, but I don't feel any religious "lawful" need to, and if I had to start observing Passover and the feast of Tabernacles, the same would apply.
So what I'm saying is, the Law, the REAL Law, is to love God and neighbour, as Jesus said, and this fulfils all the Law. The rest (the written Law), like the earthly tabernacle, is a shadow. Nothing more. Paul stated that once the written Law has led us to Christ, we have no more need of a teacher to teach us what sin is. I think conscience would give us that:
" For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another

In the day when God shall judge the secrets of men by Jesus Christ according to my gospel." (Romans 2:14-16).
The Gentiles Paul is speaking about are not non-Christians, else they could not and would not have the law written on their hearts, and it is their conscience which causes them to be obdient to the Law of Christ within them.
" So then, the law was our guardian until Christ came, in order that we might be justified by faith.
But now that faith has come, we are no longer under a guardian,
for in Christ Jesus you are all sons of God, through faith.
For as many of you as were baptized into Christ have put on Christ." (Galatians 3:24-27).
There are many other verses. Paul stating we have died to the Law, etc. It's not the Law of Christ we died to, but the shadow - the Mosaic Law with its written code.
