Small steps. I replaced my mixing bowls with stainless steel, my food storage containers that take anything warm with glass, and my drinking cup with an SS one as well. At the very least, everything looks cooler now ;)

Yeah, I'm pessimistic about the huge shift we'd need to make, especially in America. But so much of that packaging is completely unnecessary. Glass jars instead of plastic tubs or bottles. If you visit some places in the UK, they don't give you single use plastics in hotels and restaurants, though you can still buy that stuff in stores. Water is bottled in glass. Continental breakfast jams are in tiny glass jars. Some snack packages come in waxed paper bags, like what some tortilla chip brands are packaged in here in the US. Paperboard, cardboard, tins and foil. For toiletries, come countries have stores focused on sustainability where you bring your own reusable containers and they have dispensers for things like shampoo and liquid soap. Like a....soda fountain, but for cleaning products.

People are just so opposed to it here. Like aggressively opposed it it. Like eating yogurt in a glass jar instead of plastic is offensive to them. I don't get it.

It's actually not used everywhere: Cellophane is quite common as its permeable to water vapour but pretty much only that. Bio-sourced (cellulose) and compostable and you're free to throw it in paper recycling as they're used to fishing it out of the sludge (it's what transparent letter windows are made of). And compostable here means in your own backyard, no industrial high-temperature composting needed.

Many plastics can't readily be replaced but cellulose and lignin based stuff is at a stage where it can fill many many roles.

Also don't forget metal, especially stainless steel. Glass if you want to look inside. All that will need regulation as currently producers are happily externalising costs.

Now if someone would produce stailness containers that are on the same performance and general engineering level as lock&lock.
