It's getting a little tough for survivors to track down documents and elders who have been shuffled around. Difficult to investigate congregations that don't even exist anymore.
I think this is an important point, and not something I'd really considered. They could consolidate congregations and sell off KH without doing as much shuffling around. It would seem it serves several purposes: make the KH look more full, sell off KH not needed, dissolve and/or rename congregations so they can destroy records, shuffle around elders so they cannot be tracked down....
