1: The Drake Equation has so many Unknowns in it,
that it is meaningless for serious predictions.
2: Beyond that, because the Authors say so!
They do not use the Drake Equation in their story.
They do not say that Physical Laws are the same in every
galaxy or solar system in any particular universe,
they do not even say that there is more than one galaxy,
solar system, or even planet in any particular universe.
For all that they have said in the three books, the "stars"
might all be mere points of light on the Celestial Sphere!
So far, these books are Planet-bound.
