If you priced everything according to the negative externalities they cause, you would have poor people unable to afford $10/gal milk and probably pay more than the dairy farmer subsidy in healthcare costs related to poor nutrition for this entire class of people. I think nuance is needed, but the danger is that this nuance is where industries see opportunities for regulatory capture. Sometimes I think the American political system is too brittle with too much of a focus on who has the most money in the room to perform needed change. Everything in recent decades seems to be a half measure that comes too little too late.

I think the problem of poor people not being able to afford adequate nutrition has to be tackled separately. You're right that there will be all kinds of unintended effects. You're also right (in my opinion) that the US political system seems incapable of solving those kinds of hard problems anyway.
