Plastic pollution has tons of drawbacks but at least it doesn't contribute to global warming since it effectively stores carbon. Having all the plastic in the world start rotting away and releasing carbon into the atmosphere might to a lot of harm. Especially if other petrol byproducts like the bitumen of our roads are concerned. You're right however that if these products start becoming effectively unusable (or less usable) because they now rot it would make alternative solutions a lot more attractive, but we already have so much petrol byproducts in the wild that the transition would be pretty nasty.
