Courfeyrac moves to Rue de la Verrerie because he believes that it is more of a center for other people who want to move the Revolution forward. This shows how much he cares about the cause and how ready and willing he is to fight. It also shows, since there is such a large number of people ready to do the same, how badly people want a Revolution. In a politically stable country, there would not be so many people wanting to rise up against the government.
