There is nothing that you have shown that shows that Isaac was not conceived in the normal way even though it was a miracle of God....if that is the claim. Interesting parallel to Rom 9 in your point abou lying (has the word of God failed?) and 3:3 because the answer there is not genetic. It is by faith as anyone can see by the end of the chapter. Except BW. Paul was only referring to those Jews who had faith all through his treatment. That's why there is still hope held out that some will believe; there is no blanket endorsement of the genetics past or future.
"His son by the slave woman was born in the ordinary way, but his son by the free woman was born as the result of a promise." Gal 4:23. It is typically not normal for menopausal women to concieve. (and "born" here means concieved)
It is not genetic in Gal 3 either, as each concluding line of each paragraph and the whole letter and ministry and situation of that church show.
