All those laws in our Torah haKedosha about shichka, pey’ah, teruma, karbanos, shmitta, etc., etc., etc. —
WHO grew all those crops?
WHO raised all those animals?
Full time kollel guys?
Yes, if one is an ilui, if one is that guy who is maybe one in a thousand who has it in him to possibly REALLY be a gadol ha’dor, then YES, definitely go learn full time.
If not – be kovay’ah eeteem for learning, and go to work.
That IS the way for a Torah society to function.
