What makes a scam work is that it contains elements of the truth mixed with hidden lies. Otherwise it would just be ridiculous. Almost no one would sign up for the "Self Immolation Society".
Environmentalists often point out real facts, but then make a lot of false assumptions in order to get from those facts to their conclusion, which seems to always be:
"We need massive government controls on all aspects of production and consumption".
This assumes that people left to their own devices wouldn't adapt to these facts on the ground on their own. This is no different from the economic argument for state socialisms of various forms, just with different apparent problems. Again, the "right wing" plays into the scam by claiming that the facts don't exist, or that these things aren't a problem, just like with the economic argument.
The anarchist argument is that these things may well be real, but that people would solve these problems if left to their own devices, just as they always do. We don't need the state to solve our problems, and in fact, the state is often the source of the problems, by disempowering people and leaving them no incentive or opportunity to fix things spontaneously and ad-hoc.
Economics can be seen as cultural ecology. If voluntary, spontaneous order works, it will work in all areas of life. (edited because of a very good point that Rad Geek brought up, and that I will address in my next post)
