I was visiting San Diego soon after the fees went into effect and they were dealing with a cholera outbreak because the homeless no longer had plastic bags to defecate into. So you have a miniscule effect on plastic pollution in exchange for a large effect in a different area.
This is not salient, it's like saying "when I removed pressure from the wound, the patient started bleeding out. Therefore removing pressure is bad and to fix the wound we should ask
Re apply pressure" The pressure is a stopgap, you need to address the underlying problem (in this case by ensuring adequate bathrooms) rather than simply reacting to the surface level concern.
