The plastic bag is sold to businesses! If every supermarket in the world decided to never buy another plastic bag then they would no longer be produced!

There can be a futility to it all in that the “ideal option” simply isn’t produced of course.

I find boots theory is often a bit too convenient in this topic though. There is unlikely to be magic structural solutions that allow every part of your life to remain as convenient. At one point our lives will have to change in structure.

EDIT: to be extra clear, I think systemic coordinated changes is needed. I just think the “it’s the corporations doing this!” narrative to obscure the needs for reorganization of daily life on top of systemic change
