You can't just get all the people in a country and MAKE them leave this country. No. Some will resist. The monsters are similar to this. Their population is probably like a billion(assuming that they're the ONLY place where monsters thrive.) You can't just round up all these people and force them to leave the underground. No. Some will resist. So yeah, in my opinion, they can't do it unless by extreme force.
