The ban is not negative; pretending it has lead to a meaningful reduction in plastic ocean waste is. I think the reason most people are negative to the ban is that a great deal of resources has been spent on something that tries to solve a minuscule problem (0.03% of plastic waste) while at the same time inconveniencing people with disabilities for example. These resources could have been allocated to for instance a small financial reward for turning in broken/abandoned fishing nets.
