Or if they were to confirm liquids leeching plastics and made glass bottle the standard.
My concern is that the government goes WAYYY overboard, especially when you don't follow their agenda. I do not believe that to be accidental. To elaborate on your example, they'll start off with just glass. Then it has to be a special type of glass. Then it has to be molded in a certain format. Oh, and it has to have this labelling on it. And it has to have this kind of seal.
And before too long, what started out as a reasonable thing has mushroomed into the realm of stupidity and over-regulation, and we end up suffering for it at the hands of unelected buffoons.
