The idea is that society is most assured to go into a wall, so constraints are about to pop up more and more, so starting to place items / buffers here and there, ready to receive newly "convinced" people could prove beneficial.

People are followers, I firmly believe that the minute another model of society pops up, population will flip "overnight".

Also about your stimulus issue.. I also firmly believe that non modern life creates a stronger deeper and stabler set of stimuli. We just forgot.
