Counter-culture movements are an important ingredient for historical change, and they are usually catalysts for that change. Revolutionary Paris was an ideal setting for a new evolution in counter-culture: Bohemianism

Basically every counter-culture movement in history follows a certain cycle. In the beginning the movement is frowned upon -- why would the mainstream culture accept something that wanted to usurp it?

With a little time, the movement becomes chic, and some members of the dominant culture may even descend into the counter-culture voluntarily, creating a second generation of the movement. This was the case with the bohemians of 19th century Paris as it was with the Hippies of 1960's America, and so on.

Finally, the movement is accepted as an important and necessary part of the historical canon. To be frank, it goes down in history.
