The bag bans don't really have a clear objective. "The cruelty is the point" - as some like to say.
I’ve never seen one where this statement is accurate. The most common purpose is reducing litter and most of the ones I’ve seen are specifically focused on keeping bags out of rivers and oceans, and they’re quite effective at that goal. Our local rivers went from being clogged with discarded bags to seeing very few of them within a few months.
I also think you’re overselling the challenge here. Most people I know keep a couple of bags in their car/bike/backpack, which isn’t really harder than remembering an umbrella or coat.
They are just so much heavier that they don't blow around in the wind as much and are durable enough that they get bogged down. So they end up in the bottom of puddles and packed around in undergrowth. It doesn't help that they are also much darker. Them being less noticeable is not necessarily a good thing overall.
Keeping in mind a reusable bag has an order of magnitude more material in them, so even one of them contributes more plastic pollution than 5-6 crappy ones.
Either ban plastics altogether or incentivize tote loaning or something. But the 8c "reusable disposable" bag is a complete sham.
I wonder how many people even know those heavy bags ARE supposed to be reusable. I only know because I was bored and read my shopping bag.
We also have some kind of ban on fastfood giving you plastics without you asking for them first that as far as I can tell literally no one, except for a singular KFC near my house, actually abides by. It's all just ridiculous theater.
