If you're going to be dismissing well-meaning political actions with hand-waving and vague insinuations that it's ecobullshit, one would hope you could do better than just a shrug and a "beats me".
Interfering in a market and destroying an economical activity requires proof. Simply claiming "it's good for the environment" isn't enough.
It's a purely symbolic gesture, and has 0 impact on climate.
