There are many more texts than this one from Romans that tell us that the Law of Moses has been abolished. There are texts in Ephesians, Colossians, and Galatians. Not to mention Jesus' clear overturning of the Levitical food laws (e.g. in Mark 7).
I see no way to argue that the Law of Moses is still in force. True, Paul does retain the concept of law and the need to obey "law", but whatever he means by this, he most certainly cannot be referring to the Law of Moses. There is a literal mountain of Biblical evidence that the Law of Moses has indeed been retired.
We can, of course, go further on the issue of what Paul means by "the law being established" in Romans 3. But I see no argument at all that the Law of Moses still persists.
We do not have to have the Law of Moses to affirm that "sin is lawlessness", by the way.
you have many more text that tell us that the law of animal sacrifice is no more.
you have not one text from God that says the commandments or any other laws outside of animal sacrifice is no more.
if you can find one put it.
