I’m not following you at all.
Harder to get divorced = strengthens marriage
Easier to get divorced = weakens marriage
This ain’t rocket science, yo.
Certainly true. The Gemorah (as I paraphrased before) certainly does consider the feelings of the husband that his wife is planning for his death or divorce (IIRC it was by the sugyah of her selling shibudim on his land??)
However, IF doing so would help Agunos, Chazal have a track record that we do things to help Agunos that we otherwise would never do. Certainly here, where all we are doing is preparing for an Aino Mesaerv L’din, we should remove the possibility of a woman becoming an Agunah.
However, if your general viewpoint (and I strongly suspect that your Rosh Yeshiva agrees to this) is that modern Agunos are not really Agunos, as they can and should give in to all of the husbands demands to get their Get, then there would be no reason to go one Etzba past the normal Halachic line.
The reason he can’t say that is because it isn’t politically correct? There is no place for cowardice in Halacha.
