I feel like this one is just noise; mostly designed to piss people off and distract from something else, and/or add to the overall chaos.
Even if it did go ahead I'm not sure it'd make that much difference. I don't have stats handy but I don't think paper straws contribute that much to reducing overall plastic waste, it's just a nice visible way for people to think they're making a difference. I'm ready to be proved wrong on that one tho.
