It's not about"modern societies", man has been proven by several dozens of studies to not be able to consistently do rational decisions when it comes to long term. This is just about that. Also, how is that "sacrifying freedom" lmao, it just means instead of paying for infinite refill you pay for a drink, which was already the case in most French fast food restaurants. And tell me more about "freedom" when you eat in a fast food restaurant that pays their employees like, treat them like shit, bypass most working laws to pay them less and make them work more and in bad condition. If your definition of "freedom" is "doing whatever the fuck I want without any limitations no matter the consequences", then I fail to see how this is a value worth pursuing.
