Without plastic bags, I'll have to buy garbage bags (which are too large). I'll also have to carry around a reusable bag when I go shopping—which prevents me from going shopping on a whim, since I can't keep bags in the trunk of my nonexistent car—or use the paper bags which are still allowed. Ironically, this will cause me to be more wasteful, since I can't reuse paper bags!
They should just charge 10 cents per plastic bag. Heck, charge 20 cents. Lawmakers seem to have rejected this as a "tax on the poor", but is taking away the option from everybody any better?
