I think you are forgetting about time. If the rate of stuff needing to get recycle is lower, then there is more time to recycle. If there the rate is too high then the facilities are overwhelmed and resort to less optimal strategies.
It's misleading because it focuses on actions that are clearly not working. People on the average are increasing their consumption, not reducing it. That means the actual problem — the waste at the end of the pipeline — is growing every year.
Waste management is the actual problem that needs to be solved. "Reduce and reuse" can be a part of the solution, but people are not doing enough voluntarily to make it a major part.
I'm genuinely curious about your position, it's interesting.
But I can't figure it out what it'd look like in practice, might be hangover, might be I need more caffeine, whatever it is, it's on me. Don't read following as "you're saying X and thats silly!"
(A) Are consumption rates in general unsustainable?
(B) If (A) is no, are consumption rates of specific items unsustainable? For example, is the legislation you're thinking of like the deprecation of plastic bags for paper? Or something that covers a much wider amount of consumption?
(C) If (A) is "yes" or (B) is "more global", at huge scales like an economy, legislating quotas or rationing or anything at all, in practice pushes activity onto black markets.
If the concern is changing individual behavior, and individual behavior isn't changing on it's own sufficiently, what sort of legislation would change it?

Of course it is not working. The bloat and planned obsolescence of "modern software" is legendary. I had to replace the hard drive on an older computer becsuse Win 10 is slow as a dog on it, even with LTSC version and even with most of the crap disabled. And making things require the incompatible latest and greatest instead of fixing things (hello Google) , does not help either.
Maybe it's because people spread FUD about the effectiveness of "reduce and reuse" instead of convincing others that "reduce and reuse" has value as a concept.
This is why reduce and reuse are important.
