Idk, we all have our little things and pet peeves we might not be able to easily get over or personally find fun, even if we know we can suspend disbelief for far more absurd things. And "I don't like gift economies in my RPGs" seems like a pretty benign "I will not stand for it" button as opposed to people who flip out over women being allowed to have high strength scores. I feel kinda bad "Yikes"ing the person you replied to.
