a couple of points:
“I’m sure the switch to permanent remote learning can be a possibility, and even be successful.”
I doubt it, it is clear (to me and all I’ve spoken too) that remote learning is not nearly as effective as in person. This is even more true for “weaker” kids that need more individualized attention.
“The question, then, is obvious: Why not move to a cheap small town somewhere and start a new community?”
Schools is but one item keeping people in larger communities, shuls easy access to kosher food are probably the first 2.
“I’m done with high costs of living, high costs of school, traffic, the social and economic pressure of the large communities.”
So go for it!
