i think the bigger issue is probably that the paper straws are about an order of magnitude higher in mass, virtually 100% organic chemicals, and so represent about an order of magnitude higher resource consumption
the bigger issue than that is that disposable straws, even after that order-of-magnitude increase in impact, are an absolutely insignificant issue in ecological terms and yet have somehow become a political issue and spawned new laws and ridiculous greenwashing marketing
