Nevertheless, if I write something that gives you the shits, your pulse will accelerate slightly, your adrenals will uptick a little. But nothing physical would have passed between us.
I don't see how this holds. If we had you both hooked up to various types of neuroimaging devices we could see correlates of both the process of writing the text and the process of reading it. We could also predict, at the scale of neurological substructures, where in the brain activity would increase during those activities.
Communications via the internet are also understood fairly well. The entire process relies on physical theories, theories backed by significant observation.
To be sure, when you get down to small enough scales, it is unclear how language is produced, or how the electroweak force that carries your message through the internet does what we see it doing in the world, although the force is fairly well understood at the scale of transistors and fiberoptic cables relevant here. The problem of positing something extra here is, what does it help explain? And if those physical causes aren't responsible for those phenomena, why don't the phenomena of language and internet debates show up elsewhere in the world, in places where people and the internet are absent?
Part of what physics tells us is that information is protean, and it shouldn't be susprising that a code in the form of human language can be transmitted into other physical forms, especially given we have had written and spoken languages for millenia.
Thus people today stop at the laws of nature, treating them as something inviolable, just as God and Fate were treated in past ages.
I think it's understandable. Claims that don't cohere with existing knowledge should be the targets of extra scrutiny. Otherwise, you will end up with a hodge podge of contradictory claims and an incoherent science. If you accept a bad claim that is coherent with existing scientific laws, it will lead to some misunderstandings, maybe wasted research dollars, etc., but it can eventually be identified and removed.
If you let in a bunch of bad claims that violate your existing laws, you now need to rebuild the system. It becomes a web of caveats and uncertainty, making future research harder. The bar to entry should be higher, and if the phenomena is actually there, it should be able to meet this bar.
However, obviously this can go too far. Almost all paradigm shifting discoveries, by their very nature, end up upending scientific laws. Claims of woo could have been used to discourage plenty of essential theories, such as the idea that nature writes genetic traits in a language-like code, relativity, etc.
Numbers, grammatical rules, the principles of logic, scientific principles - none of these have a scientific explanation and cannot be meaningfully reduced to physical laws. They also can’t be meaningfully accounted for as products of evolution either without reducing them to biology,
This is a very interesting point I will return to when I have time. People absolutely do, with varying degrees of evidence, try to reduce logic to biology. The universe has laws that obey logic, so in turn, animals have a "logical sense," much like they have a sense of sight. Certainly some basic logical ability seems innate. Healthy human babies will register surprise when experimenters preform magic tricks in front of them that give illogical results.
However, this is a big claim made using a small amount of evidence.
I think the much larger issue here is how you can claim that science, as a system of methodologies for ensuring correct logical inference from empircle data, proves that logic comes from nature, when if logic did not obtain, we would have no reason to believe the findings of science.
This is circular. And while circularity is not always fatal (natural numbers, Liebnitz' Law, etc.) this seems like a particularly vicious circle.
Pragmatist approaches side step this circularity, but they do so by saying the best we can do is to assume that logic is posterior to the findings of science.
However, there are other issues here.
Why are the methods for proof in mathematics so different from the sciences?
Why do mechanical computing machines and electric computers get caught in endless loops due to seeming contradictions? Why is does the logical reversibility of an operation equate to entropic reversibility (there are some challenges to this)? Why does the law of information entropy, possible messages, turn out to be the same thing as physical entropy? There are a bunch of these. The whole reason quantum cryptography is so airtight is because listening in requires a contradiction, so it's not an uncommon claim that even if QM is totally replaced, the cryptographic methods will continue to hold.

These abstracts are, in fact, generated – via autopoiesis – in ecologies of (human) brains
This seems problematic as an explanation. I don't see any issue with the claim as it respects one instantiation of any of the abstractions WF mentioned, but I don't see how this can be anywhere near a full explanation.
Because is abstractions are actually just names for processes in the brain, or thoughts, it means propositions about abstractions would actually just be propositions about brain processes (thoughts or beliefs). This fact incurs a high metaphysical toll, especially as concerns predication.
For example: "Circles are shapes," seems like it has to be radically rewritten for it to have a truth value if circles and shapes are only existant as brain states.
This in turn deprives a wide array of useful syllogisms that use abstract scientific terms of their meaning. At its most expansive, the claim that language is existant only in brains, instead of being tied to a huge host of referents, reduces all propositions to claims about brain states. But then if our propositions are actually about brain states, then the claims of science that led us to believe that language is actually existant only as brain states turns out to only have been propositions about brain states themselves. O_o
Edit: I should note that the above problem is not a problem for physicalism, even reductive physicalism. It just can't be that language is an emergent phenomena of brains alone. If language is an emergent phenomena of relations between many things, including brains, but also the physical referents of language, then this problem doesn't emerge. It's also unclear if human language, insomuch as it is a code for storing and transmitting information, is unique. DNA had been around far longer than human beings, and represents a code that does many of the same things that language does.
