Your argument is a popular contrarian take, but it doesn't seem to hold up to the evidence: https://www.theguardian.com/environment/2023/jul/31/governme...

The OP was talking about "bag bans". Your linked article talks about a "bag charge". Those are totally different things.

1. People feel less aggrieved if they still can technically access something at a price. ( Less accusation of Government overreach. )
2. Economically nudging behaviour is extremely effective. People will do a surprisingly amount of work/effort to avoid even a small cost.
3. If people continue the behaviour you want to ban, you get a good revenue stream, and can escalate taxes ( e.g. Tobacco taxes )
4. It reduces the size of a black market emerging for the banned goods ( i.e. Don't make the mistakes of USA during Prohibition. )
That California didn't realise this and naively implemented a concrete ban is screwing up implementing a ban.
