> I think the world would be better off with climate vigilantes doing what they can to fix the climate.

I don't think I agree on that point. A small group of people with good intentions can do a lot of damage. See, for instance, all the attempts to introduce X alien species to a new environment to help with problem Y, and it turns out X likes its home a little too much.

I absolutely agree with your first paragraph though, and the crux of your point.
