I'm also trying to think of what use I'd make of sugar that would specifically not be for addictive purposes. Maybe keeping down medicine?

Point being, the internet is the clutchable pearl de jour for easy political points. There's far more proven addictions and harm elsewhere, but those problems are boring and trodden and don't give a dopamine hit to regulate quite like the rancor that proposals like this drum up. Hey, aren't dopamine hits what they're trying to mediate in the first place?
