Why aren't there eclipses every month when the moon's orbit is aligned with the ecliptic as a result of lunar precession?

I can understand why we don't have eclipses every month when the inclinations of the ecliptic plane and the moon's orbital plane are different. But the inclination of the moon's orbital plane changes ...
