The automotive industry, and the machines they create, produce orders of magnitude more pollution than crypto. It’s a poor choice of comparison for whatever point you’re trying to make.
Note that I didn’t say otherwise but rather that cars have beneficial effects for people outside of the automotive industry. I’d love to ban them personally but that would negatively impact millions of people unless we first made massive investments in transit, bike/pedestrian infrastructure, etc. - quite the contrast with cryptocurrency, which could disappear tomorrow without any noticeable impact outside of speculators.
