This is all fine. I'm not arguing that this is a problem for ONLY DnD... It's just that was the subject at hand, and it's a problem with DnD.
I’d say the bigger issue tends to be around certain players feeling creative or desperate and trying to lean into the plot/setting with less respect for the rules.
This is an interesting point, but I would not say that the problem is with "certain players."
DnD is heavily marketed and promoted as THE ttrpg. The default. The one for everyone. WotC talk about the game as being designed for an extremely broad pool of players, of many different styles. Players who want a more narrative experience, with less of a focus on rules are also a the target market for the system. If WotC say the game is for them, and the game doesn't handle what they want from it, then the problem is either with the game design, or with the game's promotion, marketing and reputation.
It's interesting that my post was largely about how DnD 5e fails to cater towards people who want a strict set of rules for simulations, and your argument is about how DnD fails to cater towards people who want a loose set of rules that can be bent. I'm a firm believer that when you try to please everyone, you please nobody, and this is DnD's biggest weakness as a system: If you have a strongly cohesive group of players who want a specific style, DnD will do an okay job at it, but there will always be a better system out there. It's the ready meal you put in the microwave because it's easy, not the specific gourmet restaurant that does that one dish you love perfectly.
DnD's not really trying to cater towards any specific niche though - the design wants to appeal to the widest audience possible. By trying to cater to every style, it means you can pull together a group of players with a range of preferences, and put them in the same game. That's a big part of why it's got so much ubiquity after all. The logistics of setting up a group to play are rough for a lot of people, and just being able to put a game together is easier when your system promises fun to a wider range of players.
This was the most "androgynous" looking goblin I had...
Konsi's first two years of life were as a goblin in a goblin clan, so would have eaten the same as the rest of them, after that, the next four or so years of her life were as a street urchin in Waterdeep. She ate a lot of scavenged food from trash cans and rats.
She's definitely eaten beetles.
