Mrs. tzippi:
Since when is infrastructure a reason not to do what is right (as well as their homes,etc). If the “Ir Hatorah” is not right for the yeshiva, let them move & be done.
The answer is they are accepting of the turn to Gashmius. If you want a non-gashmius yeshiva/community, perhaps lakewood is not for you; go OOT!
Besides, the housing costs saved by such a move would overwhelm any losses by sale within the frum community.
