Jesus. Imagine if we could make gold cheap enough to make into soda cans. They wouldn't even need that plastic liner. A truly infinitely recycleable solution to packaging of all sorts. Imagine if the bag on the inside of cereal boxes was made from gold foil. What's so great about gold is it's incredibly chemically stable. That means it won't interact chemically with any food you package in it. And it's an element, not some forever chemical that will pollute our bodies and environment.
I want to see a world where all cheap disposable packaging is made out of gold.
