To Sacred Driver Delight,
You said, “It is uncertain that there’s a mitzvah to live in eretz yisrael nowadays.” Please look in the Pe’at Hashulchan. I don’t have the sefer in front of me, but I seem to remember that he brings that there definitely is a mitzvah to live in Eretz Yisroel today. The only machlokes is whether it is D’oraisa or D’Rabannan. This depends on the machlokes Rambam vs. Ramban which goes back to the machlokes Tanaim about Kudsha L’shaysa vs. Kudsha L’atid Lavo.
