Another point, to counter the " plastic bags are cheap, cotton is expensive" argument, is that most of the reusable bags are plastic too. They are way cheaper to produce than cotton bags, and earn their keep within about 5 to 10 uses as opposed to 100 or whatever the crazy figure was for cotton bags.

You can use single use plastic bag 50 times or more before it deteriorates, not the thinnest kind, but the average one. They are incredibly strong. The dedicated mult-use ones are insanely strong, but also few times thicker and more unwieldy.

Like with single use shaving razor. They don't need to be literally single use. It depends on the user. You can use it as long as it serves you.

The best thing limiting access to plastic bags did was familiarizing people with the idea of taking bags to the market.
