I think the actual point is that making people personally responsible isn’t a sustainable solution long-term.
Just as an example I’ve been recycling probably 99% of plastic that comes into my home. Though I actively avoid buying products with plastic packaging it’s impossible to do this on any meaningful scale alone.
We need to incentivize producers to find better ways to package their products. If we can prevent waste at its source rather than having to convince everyone “please recycle bro” we could actually improve the world. (Also, have you seen people “sort” their curbside recycling bin?)
