A solution to a symptom, certainly... But not the disease.
If removing plastic causes this sort of thing, then something critical has been ignored. It's probably best if the society faces that problem and deals with it.
If locks are needed to protect property and safety, something critical has been ignored. It's probably best if society faces that problem and deals with it.
If formal schooling is needed to educate children, something critical has been ignored. It's probably best if society faces that problem and deals with it.
If medication is needed to keep people healthy, something critical has been ignored. It's probably best if society faces that problem and deals with it.
