Let's call it our plastic habit, or convenience. We do tend to forget reusable bags at home, and then have to take groceries home in a plastic bag. We do prefer plastic straws over reusable ones out of metal or other materials, because they have a number of benefits. We are used to furniture that's durable and easy to clean. Etc.

It's convenient to use plastics. Either lawmakers make it more inconvenient, or someone invent a comparable alternative that's biodegrading or unproblematic. Else, I think nothing will change.
