I haven’t taken the time to read every post here, so correct me if I’m wrong:
I think there’s something missing here.
Yishuv Eretz Yisrael is one of the Taryag Mitzvos.
The most relevant question for us is whether or not this is a Mitzvah b’zman ha’zeh. (As a side point there is also the question of the added benefit of being able to be mekayekm Mitzvos Ha’tluyos Ba’aretz when one lives in E”Y.)
As I’ve mentioned, none of us are going to do things according to SHU”T of the CR, but I’d be interested to hear what people have to say.
