Also, keep the set of allowed formules small.
This will serve two purposes, first, allow plastics to be actually recycled to a greater extent. Now, plastics are very much "mystery" items.
Second, it will reduce the amount of harmful and toxic additives in plastics.
Somehow we also need to stop producing so much junk, electronics which is not durable, packing material within packing material and so on. The externalised costs of so many things are huge, we need to somehow de-externalise the costs.
Another way of looking at it, is that your vision is not constructive, because you wave away the real solution as "not actionable". Parent does not propose concrete action, but neither do you. We can have meaningful discussion without everything having to be accompanied by a five-step plan.
For actionable reduction of waste, just look at how Europe has a comparable life style as the US, whilst using less resources and emitting less GHG equivalent. Not placing the EU on a pedestal. Just saying that reduction is not just possible, it's being done, as we speak. But it requires changes and is for sure a harder sell than "no need to change any habits, technology will save us".
Europe also doesn't tax "light trucks" as if they were bicycles nor force people into cars to survive.
The American mindset "I do what I do and you do what you do" worked in the 60s and 70s when people were unaware they're fucking the planet (as hard as they are), but I can't help but look down on wasteful people, they're subsidized by people doing their part (or continents doing their part)
However what I couldn't find was how much overall waste consumers create vs other sources, just this:

And it seems to imply that consumer behavior has little direct effect on the overall amount of waste we humans produce. Like, how many people would have to stop drinking canned beverages to see a decrease in bauxite tailings? Probably an unrealistic amount.
This is not axiomatic. The gases from the incineration can be put into productive use (cf. Vienna heating and providing hot water off of their incinerator), and the harmful stuff can be filtered (cf. Vienna where the incinerator is in a dense urban area, and an architectural masterpiece).
In the US, the EPA has had regulations around this since the late 70's; it's a cost of doing business at this point, not a wild new theoretical rule framework.
