We would also have torn handles, pants-staining leaks, groceries spilled across the parking lot, double and triple bagging, and so on. In fact we already have all of these problems thanks to the ham-fisted paper bag laws.

I would be more amenable to the idea if they made a bag that does not get torn (e.g. armor the paper with cotton or bamboo thread), and is leak-resistant (e.g. waxed), but that somehow takes the back seat.
