Some researcher building the next superplastic pauses to say "hey that's funny" and bam we've got a new formula that completely prevents the formation of microplastics.
Artificially constraining development is a great way to either miss an important direction of research that will unknowingly solve our problems OR just kill the industry leaving us with our existing plastics that degrade into microplastics.
Of course new developments should definitely run a microplastics study to make sure we don't make the situation worse. However "no more this until that" is a great way to freeze ourselves into our current less than ideal state for decades longer than we have to be here.
