I think that one possible reason this idea hasn't taken off is that banning plastic bags means retailers can sell their own reusable bags. Often if I go to the grocery store and forget my bags, I'll just buy a new once since they're like $1.50 at the register. Sure I could just pay the $0.10 for a paper bag, but for some reason I often don't. So now I have like 10 reusable bags in my pantry.
