I don't believe the government should be able to dictate how much someone should be able to eat or drink and regulating it is pushing that boundary. It may start with banning drink refills but where does it stop? Will the government evwntually determine what drinks and how mixh of those drinks people are allowed to buy? It should be up to the individual businesses whether or not they offer free refills on drinks, how large the portions of food they serve.
This ban does would not prevent people from drinking as much soda as they would like. It would likely make it more expensive to drink large quantities of soda though. I don't think individuals are guaranteed an inalienable right to drink any quantity of "free" soda, but I am not very knowledgeable about French law. Another way to view the question is, "Should companies be required to provide limitless soda to their patrons?" I think the answer is more obvious then- no.
These silly bands, Like France has implemented, relative to limiting refills, soda size, sugar, etc. Are completely worthless and have no practical effect except to hurt manufacturers, consumers, and worst of all, the retailer cells. Government is filled with good intentions. But we all know what the road to hell is paved with. Time for government to get out of our business.
People fought long and hard for socialized medicine. That means we all share in everyone else's medical expenses. The insurance and the hospitals can't hold it against you if you make bad life choices. For these reasons, we have a right to tell other people what they do with their lives. We gave up freedom.
