It seems unlikely that the 'ban children from a mother or a father' argument has much merit. As it didn't play a single role in the Obergefell decision. If it was going to be a significant legal issue, it would have been there. It simply never came up.
That's because all required counsel were not present at Obergefell.
All of the required counsel was present.
Remember- Obergefell was merely the 4th marriage State law that the Supreme Court has overturned as unconstitutional.
None of them had counsel representing children.
According to Silhouette's bizarre their Loving v. Virginia was never actually decided- because children were not represented by counsel.
