And I'll cut to the chase.
There is nothing wrong with the new covenant law of God (1Co 9:21),
which is the law of Christ (Mt 22:37-39) without a written code of regulations,
because in the new covenant the indwelling Holy Spirit gives one to know in his heart (Jer 31:31)
what is loving and what is not loving, fulfilling all the Law and the Prophets (Mt 22:40; Ro 13:8-10).
The Law of Christ is the summation of the Ten Commandments and it is composed of the Ten Commandments...
What you keep claiming is that some new Law replaced the Law of God. You blatantly ignore direct statements of Christ Himself...
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Luk 16:17 And it is easier for heaven and earth to pass, than one tittle of the law to fail.
And the Apostles direct statements under the inspiration of God...
1Jn 5:2 By this we know that we love the children of God, when we love God, and keep his commandments.
1Jn 5:3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
2Jn 1:4 I rejoiced greatly that I found of thy children walking in truth, as we have received a commandment from the Father.
2Jn 1:5 And now I beseech thee, lady, not as though I wrote a new commandment unto thee, but that which we had from the beginning, that we love one another.
2Jn 1:6 And this is love, that we walk after his commandments. This is the commandment, That, as ye have heard from the beginning, ye should walk in it.
From the beginning.
