Even selling their belongings and moving somewhere would be too much for most of them, and the older members would vividly remember pre-1975 if that was to happen.
Most of my witness relatives would do anything they are told to do. They called it "strict obedience." I know a lot of old timers (including relatives) who have forgotten all about the 1975 fiasco--in fact, they deny it was ever happened and refuse to look at any evidence otherwise.
