Since all of R' Elefant's problems with drinking on Purim have been true
since before the days the chiyuv was created, there is a missing piece
of explanation here.

If we accept his arguments (and as someone who doesn't enjoy drinking, I
wish I could):
How did Chazal create a chiyuv that risks piquach nefesh and chilul
hasheim?
