It's funny, one of the benchmarks I've used when trying to decide when things went off the rails was that banning CFCs was a relatively uncontroversial thing in the 1990s. Now, I agree with your pessimism.

The same rails that failed to ban coal power in the 1990s? That controversially both did and didn't ban nuclear power? And what about satanic rituals? People rightly disagree on decisions that have unknown consequences in either direction. It's not off the rails, it's just different from your personal opinion.
