Probably not, but my point in posting the clip is that "serious theologians" (e.g., St. Jerome) have maintained that celibacy is of Apostolic origin.
Others, admittedly, have disputed this. But without a definitive pronouncement from a Council or the Holy See it is impossible to maintain -- as most participants in the debate nowadays do -- that the issue is merely one of discipline.
Of course it's one of discipline. Immutable teachings cannot be changed, nor can exceptions be made to them. Both of those things have happened to the celibacy discipline.
In addition, as traditio itself points out, the Eastern Rites have "mitigated" the practice, something which is simply not possible with divine positive law.
