Your reasoning is good: why would Jesus teach something that would not last long? This is an important question to which there is no conclusive answer. The Lord Jesus taught obedience to the Law of Moses and kept it as nobody had kept before, but in the end He nailed it to the cross.
After the resurrection and before the ascension Christ told His disciples to observe EVERYTHING He had taught them. OK, but remember that Jesus taught obedience to the scribes and Pharisees. You need more? OK, Jesus told the man who was cured of leprosy to offer a sacrifice. It is obvious that the commandment given by Jesus before the ascension was not eternal. In Acts we see that many disciples continued keeping the law of Moses, but the Council of Jerusalem (some 15 years after the cross) put and end to it.
If "we uphold the Law" means "we endorse obedience to the Law" then Paul is contradicting himself because he says otherwise in many other verses.
I think the Law of Moses still exists as a reference and must the treated with great respect, but Christians don't have to keep it. Paul and other apostles are very clear about it.

I say this sincerely; Except you are ignoring His word, that they will not pass and saying they have passed...
Matt 24: 35 Heaven and earth will pass away, but my words will not pass away.
John 14:23-26, " 23 Jesus answered him, “If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. 24 Whoever does not love me does not keep my words. And the word that you hear is not mine but the Father's who sent me. 25 “These things I have spoken to you while I am still with you. 26 But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you."

SO you acknowledge that post resurrection Jesus says to teach everything He taught while in the flesh, then make reason why not to... This is odd.
You quote the "obey scribes and Pharisees" verse with deception... What does it actually say? To obey their teaching of the actual law, but not their own man made changes.... "
but not the works they do. For they preach, but do not practice"
Matthew 23:1-4, " 1 Then Jesus said to the crowds and to his disciples, 2 “The scribes and the Pharisees
sit on Moses' seat, 3 so do and observe whatever they tell you, e. 4 They tie up heavy burdens, hard to bear, and lay them on people's shoulders, but they themselves are not willing to move them with their finger.

Where are the "other apostels" clear about not obey the law? I ask you to quote one writer other than Paul that says this. It does not exist.
However I am more interested in standing the the Chief Cornerstone and His words.
John 12:48, "He who rejects Me, and does not follow My words has One Who judges him.
The word that I have spoken, the same will be used to judge him in the last day."
John 14:6, "Yahshua proclaimed to him: I am the way, the truth, and the life; no man comes to the Father, except through Me."
John10:16, "And I have other sheep that are not of this fold. I must bring them also, and they will listen to My voice. So there will be one flock, one Shepherd."
Mat 24:35, “Heaven and earth may pass away, but My teachings will not pass away.”
John 5:43, “I have come in My Father's Name, but you do not follow Me. Let another come in his own name; him you will follow.”
