> They also weigh your trash (in Dublin, anyway)
They weigh country-wide. In Ireland waste collection is done by private companies and they charge by weight. As I recall, they have something like subscription plans [1]. I'm Irish but I live in New Zealand now, and here the rubbish collection is paid for by your Council rates.
I was still living in Ireland when the plastic ban was introduced. There was push-back from some companies that make plastic bags, unsurprisingly, but it worked really well.
There was a bit of push-back here in NZ too, similar to what happened in Ireland. The usual grumbling, about interfering greenies, loss of freedoms, etc.

My wife is Irish, and they started the removal of plastic bags over 20 years ago. It was carefully phased in over time. It led to a 90% reduction in plastic bag use [0]. They also weigh your trash (in Dublin, anyway) as a means of cost pressure to reduce waste and encourage recycling. It is stated to have reduced waste by 50% [1].
