I think it would boil down to whether the disobedience was reasonable or not. My understanding was that the biggest issue was that the SSPX wanted to ensure the continued use of the TLM while JP2 wanted it to be phased out. Since the SSPX eventually got their primary goal under Pope Benedict, it seems in hindsight that it was not an unreasonable request. And if Pope Francis ends up allowing them to not accept Vatican 2, it will be even more so.
The question then becomes, was a split necessary? If the SSPX ended up getting everything they originally asked for, was the fight against them during JP2's papacy necessary at all? If it was not necessary, why was it waged at all?
But your arguement is one-sided. What about all the other differences in Vatican 2?
Using the vernacular language in the mass was a big draw to get more people and more social classes of people especially into the church. If the mass is in a language that they can understand, it's much easier to become engaged in worship, and also much easier to understand the homily.
Secondly the change of liturgical language to the native tongue put forth in Vat2 follows closely the example of the early apostles who went out of Jerusalem and spoke to the people, and were understood by them.
If i had a printer i could put forth a better arguement here, (sorry about that) but the whole point of Vat2 was to open up the church to the very people in the street that Christ was trying to reach with the message of God.
When He was here on Earth Jesus spoke to everyone from every class.
Yes, His message was first to the Jews, but God wanted to reach everyone. That's why He sent Jesus.
And that was what Vat2 was trying to do--to reach everyone; to open up the world, to involve people in the mass,
to explain about the relationship between men and women, and to talk about what submission of a person's mind
and will to God was about.
And in order to do that, when we have no other way we have to use words in a language that people can understand.
We have to look them in the eye, reach out and touch them and be with them.
Pope Francis calls that "smelling like the sheep".
It wasn't just the language, it wasn't just about the priests, or the proscribed movements, or the words of the rite.
God is so much bigger than that.
The world is so much bigger than that.
That's what Saint Pope JohnPaul II was about. He knew the dangers of not getting God's word out there and of letting Socialism and Communism take over Europe. Pope Paul IV saw it, Pope Pius XII saw it. Duns Scotus saw it, St. Therse of the Little Flower saw it, Blessed Mother Theresa saw it, Saint Faustina saw it.
All of these people saw the same need; to take the Word of God to the people so that they could know, so that they could understand, so they could learn, so that they could be comforted with the Word and with the presence of God.
Yes the Latin Mass is beautiful and it has it's place in showing adoration to God.
But the mass is not just about the priest acting on behalf of the people.
The mass is also great comfort and nourishment to the soul,
and food for the body.
And that's why we also need Vat2, because we the people have souls and bodies that are in need of God.
