So there was no special intimacy between Jesus and his mother? You jest. Even the most depraved of human sinners hold their mothers in special esteem. Murderers weep when they speak of their own mothers.
If you have come to this conclusion from a "careful reading of Scripture", then I think it's fair to say you've totally missed the beauty of the Gospels and New Testament. You've parsed Scripture to a point where it's meaning has been lost. A reading of the Gospel of Luke, for instance, speaks clearly of this wonderful intimacy. John the Baptist lept in Elizabeth's womb at the greeting of Mary.
There's a bare, minimalist, coldness in the way you attempt to confine God's plan of salvation, as if the inclusion of those whom God himself chose to participate in this plan, somehow dishonors Him. Don't put God in a box. Jesus was in no way obligated to come to us through Mary, or to live under her care in Nazareth. He could have come down to us the same way he left us; on a cloud. But He didn't. Mary brackets the story of redemption. She begins it with her "yes" to the angel and she receives the last words of Jesus just before he dies on the Cross, "behold your son".
It's an irrational, dictatorial, selfish God whom you worship. One who is paranoid that we might honor those whom He himself loved when He lived amongst us. There's almost a whiff of Islam about it.
Much in the fashion of a sixteenth-century autocratic French lawyer.
