I think the fundamental question here is whether or not you believe these large drinks cause a health problem, whether are a significant factor in driving obesity or not.
If you think that it does, then it might be a need for government regulation. You might not like it, but that's a different point from whether government regulation is beneficial or not.
We have always had government regulate our consumption--alcohol, tobacco, medicine, etc. I'm glad, for example, that alcohol is regulated to a certain extent because not only can it be dangerous to the person drinking, but it can be dangerous to me if you choose to do stupid things afterward (ie. drinking and driving).
Ultimately, I don't think it can change anyone's consumption decision if they don't want to change. If someone wants to buy a 32 oz. drink, then they can just buy 2 16 oz. drinks now. It's a little more inconvenient, sure. But nothing is preventing them from still buying the same amount they bought before.
But I do think it is a slippery slope to how far government can go.
