If that is your argument to promote the TLM, good luck.
How about this:

"Canon 27 of the New Code of Canon Law explains that custom is the best interpreter of the laws. So when we look at liturgical law in the spirit of canonical tradition, that is to say, authentically understand the law as it was meant to be understood, then it must be understood according to that tradition that has established the ecclesiastical and liturgical customs. This is how important custom is in determining the sense, the meaning, of law.
Among the ancient Fathers we have St. John Chrysostom, who says it in one line: “Is it tradition? Ask no more.”
Among the medieval Doctors we find not too many pronouncements, but what we find is unanimously taught by such as St. Peter Damien and others who insist that you must not change the landmarks. What has been handed down is not to be altered. So much so that even if the Pope should make a change in the universal customs of the Church, he should not be followed. A book dealing specifically with custom, a theological treatise written by the great Pope Innocent III, says if the Pope makes changes in the universal customs of the Church, he is not to be followed.

And then it goes even further. Cardinal Torquemada was named by Pope Eugenius IV to be the official theologian of the Council of Florence, which upheld the principle that custom governs the liturgy. Cardinal Torquemada explains in quoting Pope Innocent III — in that book I just mentioned, that if the Pope should attempt to change the customs of the Church, especially the liturgical Rites, if he were to attempt to change the Church’s liturgical ceremonies, he would commit an act of schism.
A century later, the great Suarez, who was named by Pope Paul V as the most pious and excellent Doctor, explained that “if the Pope were to attempt to change the liturgy, he would fall in schism.” This is the pontifically approved teaching of the two greatest theologians of their respective centuries. It was acknowledged that what they were teaching indeed is an expression of the mind of the successors of Peter in their Magisterium.

The Council decreed that “due care must be taken to preserve the substance of the liturgical Rites”. — Sacrosanctum Concilium, 23. Then the reform was carried out and implemented and the head of the concilium (which was the body constituted by Pope Paul VI to revise the liturgy), Monsignor Bugnini, declares that it is truly a new creation; and his right-hand man, Father Gelineau, says the Roman Rite has been destroyed. It no longer exists."
