I don't see it that way. True, as things turned out, it would have better for these people to stay. But if it had been in 1929, or 1931, 1974, or 1982, and they really could not afford to go on and lose a lot more, they would have been cooked if they had stayed.
The term scared money does not refer to the investor's personality; it refers to his situation. Hindsight is always fun, but not really fair. In retrospect these people had poor a priori asset allocations. But if we hit very stressed times again, some of us will be shown to have very poor asset allocations also.
