Nobody is ignoring the tools that are available to improve public health. Two of those tools, the ingredients list and the nutritional information, are there to support individual responsibility through informed personal choices.
It is best to understand that people can make informed choices. It is very shortsighted to think that everyone is subject to the magical sway of marketing without a conscience or decision making abilities.
The existence of personal choice and individual responsibility don't make anything else that you mention disappear. Are you saying you want to increase behavior modification of people and somehow rob people of personal choice? That's what your words imply.
