If the government requires that only metric measurements are allowed on products, companies can still produce 24oz bottles, but they'll be labeled 710ml and people will wonder... Eventually, companies will just arbitrarily size things, since people will be accustomed to measurements not making a lot of sense, and not being totally memorable.
And once again, good luck ever getting that through the courts. Because I can guarantee one company will immediately throw tens of millions of dollars into lawyers in fighting it. And they will win, because I am not aware of any clause in the Constitution that allows the government that kind of rights and powers over businesses.
Because I can guarantee that McDonald's is not going to change their flagship sandwich into the "Tenth Kilogram Burger".
Sorry, but I really have to wonder at the sanity of some people that want to force companies to change how they package things for no real reason. It is about as retarded as the "Freedom Fries" nonsense a few decades ago.
And sizes rarely made sense, it is determined by marketing. In fact, the entire reason we drink soda commonly in 12 ounce bottles is because of Pepsi. The standard drink size before then was actually 6 ounces, which is the size Coke popularized. But Pepsi first entered the national market advertising "Twice as much at the same price".
Hence, drinks commonly (worldwide) come in 12 ounce containers. Coke had to match them or die.
And drinks now come in all kids of sizes. 20 ounce, 22 ounce, 24 ounce, 750ml, 23 ounce can, 1 liter, it is literally all over the board. And the interesting thing is, you probably are not even aware of why that is in the first place.
Cost. Bottling companies try to set their volume to meet a certain cost point. That's it. That is why Arizona has used the 23 ounce can for decades, and many believe it will be the end of an era when they have to stop due to rising costs (which many predict in 2-4 years). Shasta is a lesser known bottler, and for over 20 years distributed bottled soda to the "dollar store" market. 3 liters for $1. But a year or so back rising costs forced them to reduce the bottle size to 2.5 liters.
1 liter bottles used to be seen everywhere not that many years ago. But the increase in prices has largely seen that size vanish from store shelves. I know large truckstops still carry them, but I also remember when every convenience store did also. But not anymore, the price is simply no longer attractive for those retailers.
Maybe you should take some marketing classes. It is amazing how much of this is really about psychology. Bottle shapes, colors, placement, and price are major factors in what we buy. The actual amount on the label really does not matter. But arbitrarily trying to force a change that makes no direct impact on the consumer? Yea, that just ain't gonna happen.
I simply do not understand people who have this need to mandate things onto others, other than they like to try and use force.
