I wonder if your girlfriend has made a serious study of Anarchism, a revolutionary political movement which started in late 19th century Europe as an alternative to Marxism. Anarchists reject centralised government and believe that society should function on the basis of mutual agreement. Like many political ideas it looks fine on paper but is much harder to put into practice.

Anarchists fought during the Russian Revolution and the Spanish Civil War, where for a time they were in control of Catalonia and took over the running of railways and other essential services. The paradox here is that to run an advanced industrial society with its complex infrastructure, transport systems and so on requires a high degree of discipline and order. Hardly the picture of chaos and destruction so often painted of the Anarchist movement. The workers who underwent this process would no doubt have argued that it was anarchy, because they were organising themselves without any authority being imposed from above.

People go through formative stages as their political views develope. I can't predict what your girlfriend's political views will be in the future. Everyone has to work this out for themselves. I can tell you though that anarchists come from all walks of life and all age groups and do not always fit the stereotype of the rebellious youngster.
