This, like many other ideas about roasted bean products, is a silly universalization of some individual's arbitrary preference. It's like saying that all mushrooms _must_ be minced because someone didn't like the texture of whole mushrooms at one point. Or that coffee beans must be Arabica for...reasons...when billions of people preferentially drink Robusta.
I love unconched chocolate and strongly prefer it over conched. Taza in Somerville, MA is regionally famous for their delicious, distinct, gritty unconched chocolate.
Ok. There's a difference in public discourse between "I personally didn't like the feel of the unconched chocolates I tried" and a universalized claim about what is or isn't "in general worth it" for someone else ("you"/"you're") to do.
Saying that someone else shouldn't do something because you don't like it imagines yourself as the universal subject.
