It isn't. Manipulating 60+ million people's choice architecture (as per e.g. 7) on the other hand certainly is. YMMV but either way it's still redundant if adding a tax as a market correction functions as expected. If it doesn't, there isn't a market solution so the tax is redundant. And if there turns out to be no negative externalities as per the IEA, then the whole thing is just one big Orwellian exercise in public health authoritarianism. But don't concern yourself, it's for your own good and won't someone think of the children ?
