But since when did techniques which obsessive systemizers like us use play out well with the general population..? We're not discussing what works well for a niche community of hackers, but what will work for the hundred million+ on a sustainable long term basis.

I think "perfect is the enemy of good" applies here. People en masse are not controlling their intake. They just aren't. They can't do it. We can rage about it and criticise - and many do for all the good that's doing - or we can explore options. Medications with few side effects have some appeal here. Evolutions will likely reduce those. Eventually that will not be a strong argument against the medication option is my prediction.
