> given I eat peptides every day from my food
This is briefly addressed in the article, but basically it's one thing to eat a peptide and quite another thing to inject it. Your digestive system is extremely adroit at taking peptides and proteins and breaking them down into individual amino acids, which are then absorbed via "transporters" in the gut. (e.g. SLC6A14 for glutamate and cysteine.)
If you eat insulin, absolutely nothing will happen. If you inject just a little bit too much, you're dead.
So, generally: Ingested proteins/peptides aren't drug-like, whereas they can be extremely potent drugs if administered via injection.
Granted, there are exceptions. If you accidentally get a drop of botox into your mouth, you'll be okay, but if you drink a vial, you'll be poisoned. And people have been trying to make orally-active peptides and proteins for decades, with some noteworthy successes, however few and far between in the general case.

It’s also just a silly rhetorical technique. The ability to construct a grammatical sentence of that form does not constitute a valid argument.
“Restricting nuclear material is silly given that nearly all the stuff I interact with every day contains atomic nuclei.”
I agree with some of this. There are most certainly orally active peptides such as BPC-157 and its replacement PDA penta deca arginate that can repair the gut and still circulate throughout the body especially in those with leaky gut. People with leaky gut should be able to buy a clean source of BPC-157 or PDA without a prescription and without visiting dark alleys. It is very safe and tolerable.
GLP's are all the rage these days. Doctors seem to be giving GLP peptides out like candy and those are injected. People are looking like zombies. That said if doctors are going to be so liberal with them I should be able to buy it in the grocery store and slap it down on the conveyor belt. Again I can buy things far more dangerous than any prescription drug. There are very dangerous supplements, some that are shilled heavily on youtube. For example, Glycine (for me specifically used without a specific process) is more dangerous than heroine and the vast majority of doctors would have no idea what I am talking about.
