In the context of plastic lids vs straws. While you seem to suggest that there is more plastic waste now by weight mass or quantity. There are other considerations. A lid is likely easier to see and pick up. Also a lid is potentially more likely to be less problematic for fauna whereas straws are known for being problematic (e.g. that one popular video of a straw stuck in turtle nose).

I'm not saying we shouldn't try to do better though. But there are no doubt a lot of complex variables at play
