Obviously not. For example, many monopoly companies can survive well even if the number of users does not increase. Even if there is negative growth, they are still alive and well. They don't care whether there are externalities or not.

Because no matter how monopolistic an industry is, it is not a closed system. Users in the industry will definitely have economic exchanges with the outside world.
