I wouldn’t target hfcs specifically for an ingredient ban, I’d target sugar fortifying food in general outside of reasonable expectations for the food product. (You can’t make brioche without sugar, so no one would be surprised to learn sugar was added, but they might be if they learned their ranch dressing was sugar fortified).

Hfcs is the sugar of choice for increasing palatability of food by making it sweet because it’s been subsidized so much. If you block it companies will just move to a different source of sugar. It’s not hfcs that the issue, it’s using sugar as a flavor enhancer.
