I apologize if my point on that was misstated. I was using that to illustrate that when California banned plastic bags they actually saw an increase in the amount of plastic and waste generated because there were many things the grocery plastic bags were being used for that people didn't think of.
I was illustrating the idea that just because something sounds like a simple and easy idea there is often a lot of nuance and complexity and that is involved that isn't being considered.
In general I'd say the more simplistic an issue appears to be, the more obvious the solution and the more villainous the other side seems, the less of a grasp an individual actually has on really understanding an issue.
