House of Father - 10th house or 9th house?

So, just wanted to clarify something here. 

After my last post on 10th house, the generic question asked if 10th house is house of Father or 9th house is house of Father? I am aware that many Astrologers consider 9th house as the house of Father. But here are my reasons for considering 10th house as house of Father -

1. 4th house is house of Mother. 10th house is 7th from 4th house, hence 10th house represents Spouse of Mother, i.e. Father. Just keep things simple.

2. At no time we consider 3rd house as house of Mother which may make 9th house as house of Father (7th from 3rd house). 

3. The only logic that is given in favor of 9th house as the house of Father is that 9th house is house of Teachers and Father is our 1st Teacher in life.

4. I disagree with it because all people don't have relation with their Father like Teacher and Student. Father-Child Ego Clashes and even Conflicts/Fights are common. Hence, I don't think that everyone considers their Father as their Guru.

5. Also, 9th house is 12th from 10th house. So, it actually represents Loss of Father or Absence of Father. So, whenever people discuss charts of few individuals/celebrities and emphasize on 9th house a house of Father, pay attention that in most of those people lives, there was more a case of loss of Father or Absence of Father rather than getting guidance from Father as Guru. Of course, absence of Father is going to teach some lessons too but Father is not becoming Guru, it is circumstances that is teaching lessons.

6. I have seen people losing their Father when many malefic planets transit through 9th house which again is indication of 9th house as the house of loss/absence of Father. Actually, I know a kid who was born after his Father's death and I was curious to know how the child's chart will be once birth takes place? In the end, every malefic planet in child's birth chart was impacting 9th house, i.e. loss or absence of Father from birth itself.
