Gadol > You cannot keep the next generation in a cave forever.
But define “forever”. 20 years sounded reasonable, is 200 more “forever” than 100? Many of the functions you mention can be fulfilled within the community with a Yiddish speaking travel agent or a website (der vebsait?). You don’t need to be extreme here, it will be rejected anyway, just try different pathways for some people who can handle it, and see whether the community is ready or not.
