Ah rocket stoves I'm familiar with. But it seems to me your last statement just confirmed what the original post was pointing to.
We can blame the government and the system or recognize that each of us has the power to change those systems and little bit with our choices. You prove this is with your own grocery getter. If enough people cease a practice then that practice becomes impractical, irrelevant, and unnecessary. The few holdouts that still take the bags will have no choice but to follow or else learn to juggle.
The problem is one of awareness and apathy. Changing those two things requires education obviously for the next generations and reprogramming for current ones.
Additionally as a minimalist (like hardcore as shit with literally everything I own in a backpack for the better part of a decade minimalist) I have no problem pointing out that in much of the "developed" world people use way too much shit. Television and Internet ads, pop culture, parents and friends condition people to equate their identity and value to things. This is a major flaw in the system and hurts all of us in the long run.
Our obsession with status through materialism has potentially cost us great advancements in knowledge and understanding.
