why would the chiyuv of talmud torah include a chiyuv to become a talmid chacham? Does it require you to become a sofer also? Does the chiyuv of tefilin require you to become a tefilin macher? Do the halachas of treifos require you to become a shochet? There is no chiyuv to become a talmid chacham. When the gemara talks about halachas of chaveirim and tzurba d’rabanan the connotation is that these people were there by choice.
