Direct Collapse[1] models provide candidates for this, no?

With the size of quasars we're seeing in the early universe, direct collapse seems likely.
Of course this begs the next question of how didn't the universe just collapse back in on itself!
Inflation seems to have been tuned to ensure this didn't happen, giving the cosmos time to grow while ensuring it didn't grow so quickly that galaxies couldn't form.
Cosmological natural selection provides an explanation for this, too.
"Cosmological natural selection provides an explanation"
This is the biggest reach in your entire essay, that black wholes create new universes. The event horizon is complete cut off from this universe and speculating that generations upon generations of universes are created from black holes is fanciful. Your just shoehorn what is basically a massive anthropic principle onto an interesting cosmology theory unnecessarily.
