-SNIP of a big rant on free will-
Your reasoning has one rather large flaw.
THERE IS NO SUCH THING AS FREE WILL.
'Ahem' let me rephrase that, 'free will' the complete freedom to do what you want is impossible in today's interconnected society for it will inevitably conflict with the choices and will of others. For example: Someone wishes to have a bonfire during their party in the middle of a complete fire ban. His wouldn't be able to proceed with his 'free will choice' due to the risks and cost it posed to the rest of society.
Of course you could argue with that your choice of a drink does't do squat to anyone else directly like a massive firestorm and you're correct. However
indirectly you are with higher tax rates (or insurance premiums) needed for medical services struggling to cope with peoples 'choice' of being morbidly obese.
Our world has become so interconnected that YOUR choice will have an affect, especially combined with millions of others making the same decision. So yes the ban on gulp style servings will restrict your freedoms, but so did your parents/caregivers did by stopping you from running into oncoming traffic/sticking things into power sockets etc.
That does however raise the question of WHO's decision is correct i.e. Censorship and assorted 'Big Brother' style laws but that is for another thread.
