It’s this. They dream of having what is essentially a side hustle that conforms to an escapist fantasy that conveniently nests within their current ideology. It’s the maximum level that they can “escape” the rat race of the rest of reality but if they fuck up they can still reintegrate like you pointed out ala the grocery store or using their primary income to offset the losses. Hell, a lot of these will probably just be vanity projects of one spouse where they probably get burnout once they realize how much work it takes to do it themselves. If they really did get that land watch how many of them would just eat the losses to have a big fucking yard because it’s not their real source of income. In a generation they’d turn 40 acres and a mule into golf courses and subdivisions.
