I wonder at the wisdom of maintaining villages with increasing cost to the public.  If a place is not self-sustaining, should it not become deserted? Just about everything rural is more costly, so if people elect to live there, should not they bear the cost of their choice, themselves?
I'm sure there are strong arguments  pro & con, but it might be time to lay them out.
The eroding villages that want to be moved ... everyone should have some input in these costly issues.
