What if the asymptotic initial state was that an entire infinite space was infinitely dense?
In this case due to the near uniformity there is no strong affinity for black holes creation, and due to the same uniformity, there is no need for superluminal inflation to overcome gravity.
However, superluminal movement of the space is what is currently believed to be the state now and during the big bang, so as long as it is given for free (according to observations and according to Einstein's cosmological constant that predicted it), it can be used.
