takehmamash,
i dont think theres a mitzvah to live in a place if it’s not feasable to provide for oneself withouut assistance from others (correct me if im wrong) if it says by shabbos aseih shabboscha k’chol v’al titzareich l’briyos by shabbos all the more so by eretz yisrael
secondly, you mentioned miami specifically
There is no kedusha in Miami.
but now you’re saying eretz yisrael is more holier because it’s eretz yisrael meaning even new york has no kedusha
