The answer to your first question is more philosophical, and I think outside the scope of what I am able to reply to here.

But for the second, I think while there are similarities, the details are awfully important for galaxy formation simulations. That being said, there have been comparisons between large scale structure and things like slime molds [1], but beyond techniques we do not expect identicality to the level of precision that is the current state of the art.
