What I mean by “non lmaaseh” are sugyas in shas that most probably will very scarcely be nogeah to our daily life. I understand that to learn these sugyas well will give us a deep understanding of how to think in learning and also take us on a journey to understand the depth of HKBH’s holy Torah. But the bottom line is this: in yeshivas bachrim are encouraged to learn these things and not really pushed to have a set seder in Shulchan Aruch, the outcome of this are bachrim knowing some sugyas well but at the same time violating shabbos unknowingly! Is there some reason for how we can allow such a thing and why minhag Yisroel has become to learn this way?
(Specifically looking for mekoros from rishonim / early mid achronim whom agree with such an approach to this learning)
