My point is that the salt doesn't have to be just salt. Folks who don't like fish sauce can find something that works for them.

Yes, I like miso and soy sauce too. Salt + umami = yum. But the salt is the vital part for low carb eaters like me. The "keto flu" is no joke. I'm not even a keto person (not that strict) but I've had weakness, headaches, cramps, and heart palpitations when I had insufficient electrolytes. I don't want to repeat that!
