Is there a jurisdiction somewhere where using plastic straws has been made a criminal offence with jail time as a punishment?

Here (Australia) it was implemented as a civil fine and I assumed it would be similar elsewhere. But if that were the case where you live I’d agree that’s awful.

If that’s not true then you’ve just made a straw man argument.

Hell, even if there _was_ a place where they locked someone up for providing plastic straws to customers I’d argue that the issue is that particular law. Not the broader issue of legal ‘nudges’ to foster positive cultural changes.
