poly: Fermi Paradox and Smolin's selected universes

 I recently read Lee Smolin's _The Life of the Cosmos_, which describes
his theory that black holes generate new universes with slightly different
parameters, which implies that natural selection causes typical universes
such as ours to have parameters that maximise black hole formation, which
also happens to be more conducive to the existence of life than many other
possible universes.

 I am wondering whether this reasoning can be extended to address the
Fermi Paradox by hypothesizing that life capable of solar-scale engineering
will find matter to be more valuable outside of black holes than inside,
and significantly reduce the number of black holes produced by universes
in which they arise. This should imply that natural selection will cause
the expected number of such civilizations that arise per universe to be
slightly below 1.
 Does anyone see flaws in this hypothesis?
