So we need to hire more police just to mitigate littering? Doesn’t sound like a smart solution tbh.

In the short term yes, but probably not their only duty. Want the problem solved in the real world or not? Hoping doesn't work, as has been demonstrated.

Also, in country where societal trust has broken down, it could only be successful as part of a larger strategy to fix that first.

Presumably after a culture of cleanliness takes hold, "litter enforcement" would drop off.

I think it’s smarter to just ban packaging that will be around 100+ years.
