I think you're overestimating the effectiveness of guerrilla warfare. Guerrilla warfare isn't this magical thing that when applied is guaranteed to work. If it were, it'd be a conventional strategy. Guerrilla warfare is a thing borne of desperation, or helplessness. When people have no other way to fight and need to resort to hit-and-run tactics to combat overwhelming opposition. Sometimes it works, sometimes it doesn't. It is not an especially effective strategy that works every time, or even most times. If it were such a strategy, no-one would fight any other way. It's also a strategy that is reliant on things like the environment to succeed. Look at where guerrilla fighter groups are most successful: Colombia, Africa, Vietnam, Iraq. All of these are places where the environment is in favor of guerrilla fighters because it allows them to hide well, and where the lack of infrastructure works against professional armies.

Not to mention a guerrilla group still needs significant numbers to succeed.

But regardless of any of that, the point is we can't have any more rebellions in the US. It's had enough. They are a hindrance. We need to let the US become important, especially now that we have a player that is doing such a great job at bring it back to life.
