I see three possibilities so far: 1) creating the baby universe destroys the parent universe (e.g. finetuning the black hole collapse requires ultra-high-energy processes causing a vacuum decay outside the event horizon); 2) galaxies are organisms and only a few sites function as “germ cells”, the rest of the galactic mass is needed for other functions; 3) there are bounds on the fidelity of large-life heredity (as mediated via this process), producing an inescapable variance in their enthusiasm for replication, and most of the time reproduction is only a secondary imperative.
And yes, I’ve drifted from “cosmic immune system” to “cosmic reproductive cycle”. Perhaps there are other hypotheses, where we are involved with the “cosmic gall bladder” or “cosmic toenail clippings”. :-)
