I don’t understand how one part of the post relates to another. Yeah, sure, computational irreducibility of the world can make understanding of the world impossible and this would be sad. But I don’t see what it has to do with “Platonic laws of physics”.
Current physics, if anything else, is sort of antiplatonic: it claims that there are several dozens of independent entities, actually existing, called “fields”, which produce the entire range of observable phenomena via interacting with each other, and there is no “world” outside this set of entities. “Laws of nature” are just “how this entities are”. Outside very radical skepticism I don’t know any reasons to doubt this worldview.
By “Platonic laws of physics” I mean the Hawking’s famous question
What is it that breathes fire into the equations and makes a universe for them to describe…Why does the universe go to all the bother of existing?

I am not sure if it actually “claims” that. A HEP theorist would say that QFT (the standard model of particle physics) + classical GR is our current best model of the universe, with a bunch of experimental evidence that this is not all it is. I don’t think there is a consensus for an ontological claim of “actually existing” rather than “emergent”. There is definitely a consensus that there is more to the world that the fundamental laws of physics we currently know, and that some new paradigms are needed to know more.

No, I don’t think that is an accurate description at all. Maybe I am missing something here.
