How would you know what was in Jesus' mind? He never defined the structure of what is now Holy Orders. He allowed the Church to do that. There were no priests among the apostles; in fact, they didn't even call themselves "bishops." And there was constant conflict among the apostles as to who had how much authority. That even involved Peter, though no one challenged him as the "Head." Organizationally, the Church could constitute itself differently, as long as the Pope remained at the spiritual center of the episcopacy, as the first among equals.
Well, if Jesus allowed the Church to define its organizational structure, if the Church chose the monarchical form, and if the Church is guided by Jesus, do you think Jesus would have had some other form in mind?
