After Jesus fulfilled the Mosaic Law, the quantifier of Heaven and earth passing away in His statement…and His statement was clearly pertaining ‘specifically’ to the Mosaic Law…was negated. Jesus wasn’t referring to the end of time or anything else. “When the cows come home” and “When pigs fly” are also quantifiers that people use nowadays to add emphasis to certain aspects of a statement they’re making. They don’t mean them literally, and neither did Jesus.
No need for you to apologize for your circuitous logic; and it’s OK with me for you to believe whatever you choose. The Mosaic Covenant…along with its 613 commandments…has most definitely been retired. Jesus Himself replaced it with a better covenant ~ the New Covenant.
Peter and James, both church leaders, clearly disengaged the New Covenant ekklesia from the value system, the worldview, and especially all of the 613 commandments of the Law of Moses.
