No, I would retreat from such logic. I am just pointing out the seriousness of papal disobedience. It is a grave offense to break one's vow to the pope as the archbishop did, and it is a mistake for a serious Catholic to ignore the admonitions of the Holy See. I apologize for having created any confusion.
The offence is consecrating bishops against the will of the Pope, an act which denies that the Pope is the head of the College of Bishops. There is no circumstance that can give rise to a "necessity" for consecrating bishops against the will of the Pope.
