Toi –
Nu nu. I don’t agree. One can get the same havanah by having the translation handed to them and toiling on a cheshbon in Tosafos, on the Beis Yosef Shach and Taz, on the Shmaytza and the Ketzos. I do not believe that struggling with teitsch is a necessary prerequisite for havanah. If it were, all of us who can read straight through a Gemara without an Artscroll but without a struggle would have a problem.
