Bootstrap model and different laws?

In summary, physicist Geoffrey Chew proposed the bootstrap philosophy in relation to S-matrix theory, which denies the existence of fundamental laws of nature. The universe is seen as a dynamic web of interrelated events, with no fundamental entities or laws. This concept was initially met with skepticism, but eventually gained popularity as a theory of strong interactions until quantum chromodynamics came into play. The bootstrap idea is based on consistency conditions and suggests that there is only one set of laws that govern all physics in our universe.

TL;DR Summary
Does Chew's bootstrap idea accept the possibility that there may be infinitely many possible laws of physics?
Physicist Geoffrey Chew proposed the concept of bootstrap (related to S-matrix theory) where he denied that fundamental laws of nature existed at all, as it is indicated in a writing in his memory written by one of his collaborators ([https://www.fritjofcapra.net/in-memoriam-geoffrey-chew/])
"*The bootstrap philosophy abandons not only the idea of fundamental constituents of matter but accepts no fundamental entities whatsoever — no fundamental laws or equations, and not even a fundamental structure of space and time. The universe is seen as a dynamic web of interrelated events. None of the properties of any part of this web are fundamental; they all follow from the properties of the other parts, and the overall consistency of their mutual interrelations determines the structure of the entire web*"
I see an apparent conflict here that I would like to resolve:
If one denies that fundamental laws of physics exist, then we could claim that the universe could have been extremely different (since if fundamental laws do not exist, nothing would have prevented the laws of physics to be extremely different and therefore a universe without e.g quantum mechanics or a very different version of quantum physics could have been born)
But then, from what I have read, the bootstrap idea is based on only consistency conditions and therefore we could claim that the universe could not have been different because the only set of possible laws is the one we have.
So, according to the bootstrap idea, if there are no fundamental laws of physics, could the universe have been born with completely different laws? Or does it admit only one set of laws, being those which govern all physics in our own universe?

I'm not sure I can answer your question particularly well, but I happen to have just come across the concept of S-matrix theory and the bootstrap framework myself quite recently in an interview with the late Murray Gell-Mann, who was an original proponent of the scheme. The part on S-matrix theory starts here, and he says here that Geoffrey Chew was actually quite resistent to the idea at first, as he couldn't see how the consistency and unitarity conditions, observable dispersion relations and other general rules could actually be used to describe any particular theory (to be honest, I can understand his initial skepticism), but eventually came round to liking the idea.

By the way, that video series as a whole is an incredibly interesting first-hand account of physics as it was evolving in the 1950s and 1960s. The bootstrap picture was very popular as a theory of strong interactions until quantum chromodynamics started to take shape.
