I can't speak for other countries, but in the US trying to get everybody on the same page in terms of recycling habits would be worse than herding cats.
It's not something anybody wants to put energy towards because they're trying to keep 50 other plates spinning at any given time (which as an aside, is also a huge source of plastic waste because nobody has the time or energy to cook) and there's also a chunk of the population who will take any kind of push to change behavior as a personal affront.
You can probably get a small percentage to adhere fully and a slightly larger to partially adhere, but I agree with parent comments that it's better to make companies use materials that are easier to recycle in the first place.
I don't disagree with what you're saying, but it isn't mutually exclusive with having the government do what it can do educate the public in order to get them behave more responsibly and civically minded. Obviously this would require a bit of a re-think in terms of what we value as a society. Doesn't mean that it isn't worth trying.
