I think it's a little social experiment like training. During the first “night of the long buckets,” the people were indignant, protested, and seethed. During the second, almost everything was quiet, and the number of “refusers” from self-demolition was counted in just a few. Then they will begin to obediently destroy everything themselves, then they will slowly begin to rejoice, and then they will insist that their buildings must be demolished as soon as possible. That is why they do not demolish everything at once, but in parts. It's not like a dog's tail. Here, the more parts you cut off, the greater the pleasure.
