A tribial point of the Maruyama's paper

I've just finished reading the Maruyama's paper.
He tells about Japanese libertin in the Tokugawa era, like Kaiho Seiryo or Hiraga Genai. He says that they satirized square authoritical scholars but were not dangerous for political power. Parhaps Maruyama sees something same with ex-leaders of the late 1960s "student power".
